‎OB Wheels on the App Store

Description

Does the world need another OB-wheel-due-date-calculator app? You bet! OB Wheels combines three things that clinicians need to derive all the dates necessary in pregnancy care, and no other app has this combination.

It contains a calendar calculator to determine EDD (EDC) from LMP or from a sonogram report. The calendar calculator also provides gestational age (EGA) as of any date for a given EDD or LMP. Because the calculator works off the real calendar, it is accurate for leap years too.

Then for all of you who miss your cardboard OB wheel, the app contains one which you can rotate, pinch and zoom, and generally play with just like a regular cardboard wheel. It's a little tricky to learn how to plant two fingers and rotate them rather than pinch-and-zoom to get rotation versus resizing. But the wheel works and it is accurate, especially so because you can zoom in to be sure where the little date hash lines lie.

Finally, the app notes the most recent committee opinion scheme from ACOG on how one might reconcile due dates from LMP and sonograms to arrive at a single final EDD. To my knowledge, the scheme is authority-based and no better or worse than other schemes, but my practice and my learners need a single clear scheme, so this app includes one for easy reference.

As an educator and clinician myself, I am grateful for feedback. Email me via the contact email at my website.

Version 1.2

This app has been updated by Apple to display the Apple Watch app icon.

the due date calendar calculators!
- totally redesigned
- much easier to use
- much easier to understand
- exactly what you expect from an iPhone app
- sorry I didn't improve this app earlier (but I didn't know how, still an amateur programmer)

Difficult to use

OB nurse for 20 years. Enjoy the online calculators rather than looking at a wheel. Neither of the applications within the app were easy to use to find the gestational age. I went looking for another.

It IS tricky to use, but it DOES work

So, the app has two functions. One is the Calendar Based Calculator and the other is the Traditional OB Wheel. The OB Wheel is REALLY tricky to use (the app says it so itself in the Wheel window) and does take a lot of practice to get the grip of it, but does work like any other cardboard wheel. The calculator is digital, so I don’t understand how anyone can have problem using it or find it complicated, except that don’t know how to properly use their phone and/or have little fine touch skills.
To the developers, thanks for making this nice app and leaving it free of cost. As a suggestion, maybe if it were compatible with iPad it would be easier for more users to be able to work with the Traditional OB Wheel, as the screen of an iPhone is kinda small (even in the iPhone Plus) to maneuver it. Nevertheless, very helpful.

Works great

I don’t understand all the negative reviews. You put in the LMP or the ultrasound Dating and it tells you what you need to know. Simple as that. Tells you when to use U/S vs LMP also. The “wheel” is clunky and kind of pointless if you ask me. I always just use the calendar based calculator.

How long does pregnancy last in dogs - symptoms and signs of pregnancy in a dog

Owners who want to get offspring from their dog need to know how to determine the time for mating, how long the pregnancy lasts in dogs, what kind of care is needed and what complications are possible.

When is fertilization possible?

The cycle of the reproductive system of dogs is different from the human one. The development of the egg takes place in four stages:

proestrus - lasts 1-1.5 weeks, precedes the release of the egg, swelling of the vulva occurs, slight bleeding, the female attracts males, but does not let them near her;
estrus - lasts from 5 to 20 days, the egg is released, the discharge brightens, the female is ready to mate;
diestrus - lasts up to 60 days, the body produces progesterone, but fertilization is no longer possible;
anestrus - a period of rest, the female does not let her in and cannot become pregnant.

The egg matures in the dog's body only 2 times a year. Fertilization is only possible during oestrus. But it is not always possible to accurately determine its beginning and end by external signs.

Pregnancy in dogs: duration in large and small breeds

The duration of pregnancy in dogs is from 56 to 70 days from the date of conception. Small breeds carry puppies for 56-63 days, large breeds - 67-70. But, as in humans, premature birth or gestation for more than 70 days is possible. There is no need to panic if labor began earlier than the date you calculated or does not begin at week 10 - you may have made a mistake when determining the date of conception. 2-3 weeks before the expected due date, prepare the site, visit the veterinarian to make sure that the pregnancy is proceeding normally. Be sure to arrange a visit with him if complications arise during childbirth. After examination and ultrasound, he will more accurately determine the age of the fetus, whether there is a threat of premature birth or violation of labor activity.

First signs of pregnancy

If the mating was successful, after 10-14 days you can notice the first symptoms of pregnancy in dogs:

change in behavior - some animals become more sociable and affectionate, more often ask the owner to pay attention to them, others deteriorate in character, irritability appears;
worsening of appetite, nausea, vomiting, like in women, dogs have toxicosis due to the restructuring of the hormonal system, but if it does not develop, appetite may increase;
increased sleep duration - the expectant mother often refuses to play active games, tends to lie down;
darkening and swelling of the nipples - at the first puppies may appear after 3-4 weeks.

An increase in body weight and abdominal volume occurs at 5-7 weeks. But if a false pregnancy of a dog develops, the signs are no different. The veterinarian can accurately answer the question, real or false, after an ultrasound and a blood test.

What changes should be made to the diet?

During pregnancy, dogs should follow the recommendations of the veterinarian on the composition and caloric content of the diet. It takes into account the breed, weight before conception. Animals that tend to be obese or underweight are fed differently. Both nutritional deficiencies and overeating are dangerous. In the diet, increase the content of protein products (meat, fish), and reduce carbohydrates. If the gestation period in dogs is more than 4 weeks, increase the frequency of feedings to 3, and from 6-7 weeks to 4, but reduce the portion sizes.

If feeding dry food or canned food, tell your veterinarian the line and brand you are giving your pet and ask if he needs nutritional supplements. When feeding fresh food, they are essential. The veterinarian will recommend nutritional supplements that compensate for the lack of vitamins, minerals, amino acids, the need for which increases during gestation. They are added to food or given separately.

Care

During pregnancy, dogs need to increase the frequency of walks. Growing fruits put pressure on the bladder, the pet often feels the desire to go to the toilet. With toxicosis and when the volume of the abdomen increases, she gets tired faster, does not want to walk for a long time, play active games. Do not limit the activity of the dog, but if he often lies down or turns around and leads the owner home on a walk, give him the opportunity to rest. Do not walk for a long time in the heat in the sun.

Keep the bedding clean. Wipe your paws after walking. Bathing a pregnant dog is undesirable, but if she likes to take a bath, use only a special shampoo, dry it well or dry it with a hairdryer, protect it from drafts.

Prepare a place for childbirth and raising offspring, make sure that it fits the expectant mother. It should be secluded, protected from drafts, direct sunlight, not too close to the battery.

Pathologies of pregnancy

Due to the characteristics of the breed, age, unsatisfactory conditions of detention, anomalies in the development of internal organs, certain diseases or infection with helminths, pregnancy pathologies develop:

false - egg fertilization does not occur, but the body produces hormones, as when carrying puppies: toxicosis, swelling of the nipples, colostrum production, an increase in the volume of the abdomen may develop, the pet builds a nest and shows maternal instinct in relation to soft toys, other animals;
frozen - one, several or all embryos die, with the death of several fetuses, the rest can develop normally and be born healthy;
ectopic - the fetuses begin to develop outside the uterus, which is accompanied by painful sensations, bloody discharge.

What to do with pathological pregnancy?

False pregnancy is not a disease. The hormonal background normalizes without treatment, the help of a veterinarian is required in the development of inflammatory processes in the uterus or in the mammary glands, if the animal suffers greatly or its behavior is dangerous for others.

If the embryos die, a miscarriage may occur, purulent inflammation may begin, or the pregnancy will proceed without changes. The death of embryos can be detected by ultrasound. The veterinarian after the research will determine whether there is a chance to keep the pregnancy and get viable offspring.

If you suspect an ectopic pregnancy in dogs, you should immediately contact your veterinarian and do an ultrasound. If the diagnosis is confirmed, in order to save the life of the animal, the pregnancy is terminated (with medication for a short period, after 3-4 weeks, an operation is performed).

Vaccinations and deworming

When planning to get offspring, check with your veterinarian what vaccinations you need to do before mating. After conception, administration of vaccines that are safe for adult animals can damage the embryos, cause congenital malformations of internal organs, or death. Due to the high risk during pregnancy and lactation, vaccination is not carried out, so sometimes the timing of some vaccinations is shifted.

Deworming should be carried out 2-3 weeks before mating, but not earlier than three months after the previous intake of anthelmintic drugs. They are prohibited for the entire duration of the dog's pregnancy and feeding of puppies - more than three months, so it is important to deworm at the optimal time before mating. The next dose of anthelmintics is prescribed after the puppies start eating solid food.

How can you tell if you are about to give birth?

Often in a day you can determine that the body is preparing for childbirth. There are specific transparent or yellowish discharge from the vagina. The dog often sits down, becomes more active, seeks the company of people, fawns, or vice versa, does not leave its place, refuses to eat, after a short walk it asks to go home. You can find out about the approach of childbirth by regularly measuring the temperature - in 20-24 hours it will drop by 1-1.5 degrees. Calculate how long the dog is pregnant to see if the birth is normal, premature, or delayed, when veterinary care is likely to be needed. Stay calm and calm the dog, decide which family member will constantly monitor his condition. Soon cute healthy babies will appear in your house.

Calculation of pregnancy online mobile version. Calculation of the date of delivery

(duration 28 days), or 280 days. In fact, these terms fit into 9 calendar months, plus seven days. Therefore, it is customary to talk about 9 months. The birth of a baby at 38-42 is considered normal if there are none indicating immaturity or overmaturity. If the child was born later than this period, then it is considered post-term, otherwise - premature.

Obstetrician-gynecologists start counting the gestational age from the first day of the last menstrual period. Usually, the actual period is 13-16 days less, since conception occurs approximately in the middle of the menstrual cycle, i.e. at the time of ovulation. However, to avoid confusion, doctors start counting the gestational age 2 weeks ahead of the date.

If you do not know the exact date of conception, then it is most correct to count the weeks of pregnancy according to the results of ultrasound. Scheduled research is carried out at 12-13. As a rule, it coincides with the deadline set at the first appointment. But, if there are discrepancies, then it is better to focus on the period set with the help of ultrasound.

In some cases, there may be a discrepancy between the size of the fetus and the gestational age. For example, as a result of polyhydramnios, the presence of tumors, etc. These data are taken into account by specialists in the study. In this case, they put the number of weeks of pregnancy, obtained from the calculation from the first day of the last menstruation, and with the help of ultrasound at later times, they correct it.

The question of how to determine the date of delivery often causes discussion and controversy among pregnant women. The difference between your own calculations, the terms that are set during an ultrasound examination and those that the doctor writes on your card is completely confusing. Specifically, in order to at least a little, but still make life easier for pregnant women, we have developed a program that independently calculates the estimated date of birth. Now you don’t have to visit a doctor or bother yourself with mathematical calculations, just to calculate the date of birth of your baby, you just need to enter the number in the right column of the calculator when your last menstruation began.

Negele's formula is a two-step puzzle.

The program that allows you to calculate the date of birth is based on the Naegele formula, named after the German obstetrician who first proposed using this simple calculation method. It is known that pregnancy lasts an average of 40 weeks from the beginning of the last menstruation or 38 from the moment of conception. Negele simplified the calculations by reducing them to a few simple arithmetic operations - remember the date of the onset of menstruation that preceded pregnancy and subtract 3 months. You need to add 7 days to the resulting figure - this number is the same date of birth.

The question often arises - why should the calculation of the date of birth be based on the date of the last menstruation? This tradition, generally accepted in obstetrics, is justified, because not all women know exactly the day of ovulation, while most keep a calendar of menstruation. Bewilderment is also natural - after all, in the first, so-called "weeks of pregnancy", conception has not even occurred yet. Yes, this is true, and this period refers to the gestational age conditionally, for the convenience of obstetrician-gynecologists, according to the standards. The fetus begins to exist when it is already behind about 14 days of pregnancy. If you reliably know the date when fertilization occurred, you can calculate the date of birth yourself by adding 266 days - this is the average gestation period.

Is the deviation from the settlement date normal?

It is worth noting that the expected date of delivery for you is nothing more than a guideline. In fact, about 17% of women give birth on day X, the remaining 83% a little earlier or later. Predicting the onset of labor is beyond the power of any specialist. Moreover, normal, urgent births, that is, births that occurred at physiological times, are those that happened from 38 to 42 weeks of pregnancy. Often there is an unpredictable post-maturity or prematurity of pregnancy. Premature labor can be provoked by deviations in the development of the fetus, pathological processes in the mother's body, stressful situations, hereditary factors, and many other reasons. Therefore, it is very important to understand that the calculation of the date of birth is a very conditional concept, regardless of the method used

However, there is some regularity, taking into account which we can assume the development of the situation with a healthy pregnancy - the longer the monthly cycle, the longer the pregnancy lasts. Before you determine the date of birth, taking into account your individual characteristics, remember the duration of your menstrual cycle - from the first day of one period to the first day of others. If the cycle is longer than the standard 28 days, the pregnancy will probably last more than 40 weeks, and vice versa. Keep in mind that we are talking about the transfer of the estimated date of birth by no more than 5 days.

The calculator will help you calculate your due date from your monthly period as accurately as possible, but remember that the data obtained from a medical examination is crucial, as it is more reliable. The reason for this approach is that menstruation is easily confused with bleeding that opened after conception and spontaneously stopped. Also, when examined in the third trimester or ultrasound of the uterus, the doctor can observe the degree of maturity of the placenta, the position of the fetal head in relation to the entrance to the small pelvis, the opening of the cervix, signs of full-term fetus and many other important data. By all these parameters, one can judge the readiness of the fetus and uterus for childbirth and the likelihood of their early onset. In addition, focusing on the size and proportions of the fetus during ultrasound, the doctor sets the age of the fetus in accordance with.

Pregnancy calculators

The calculator calculates your pregnancy based on your last period. The gestational age is obtained in "obstetric" weeks.

As a rule, each pregnant woman has her own calendar, where she enters all the necessary data, outlines important dates, and takes notes. With its help, the gestational age is usually calculated.

Given the nine-month duration of this period, paper calculations seem to be a very routine task. But modern women live at a great time - they are not at all obliged to keep such a calendar and do tedious arithmetic, unless, of course, they are so sentimental that they decide to keep their weekly notes as a memory of the wonderful time of gestation. You can safely entrust the program to take care of calculating the gestational age. Indeed, for those who prefer to spend their free hours on activities that are much more useful for the future baby and his mother, there are numerous virtual services like this one (we hint at our calculator).

What do you need to calculate the gestational age?

In order to calculate the gestational age right now, you only need to remember the date when the last menstruation began and enter it in the appropriate form fields. This number is the starting point of your pregnancy. We are talking about the so-called "obstetric weeks" - all over the world it is customary to count pregnancy in this way, although fertilization occurs only in the middle of the cycle. This measure is necessary for the convenience of doctors, but often causes surprise and misunderstanding among patients.

It is worth noting - during an ultrasound examination of the fetus, you will come across the fact that the known gestational age can be calculated differently - by weeks of fetal life, that is, from the day of conception. You may even find an entry on the ultrasound results sheet that lists both dates. In order not to be embarrassed by such contradictions, feel free to ask the doctors what kind of gestational age we are talking about, real or obstetric?

It is very important to emphasize that even if you know the exact date of conception of the baby, in order to calculate the gestational age using the calculator, you need to use the date of the last menstrual period. If you find it difficult to remember, count 2 weeks ago - with a standard 28-day cycle, ovulation most often occurs on day 14.

I don't remember when I had my period. What to do?

Sometimes it happens that a woman does not know when she had her last period, for example, she does not remember, does not follow the regularity of the cycle, or has just stopped taking contraceptives. If you have no idea what your gestational age is, it can be calculated at. The data obtained in the early stages (up to 12 weeks) have the greatest reliability, when the rate of development of the ovum is still very high and changes are noticeable literally every day. The size of the fetal egg alone, without taking into account the proportions of the fetus, will tell the doctor a lot. At later dates, errors of up to 2 weeks are possible.

Another very informative method that allows you to calculate the duration of pregnancy is biochemical - a study of a woman's blood for the content of hCG - human chorionic gonadotropin. This hormone is produced by the fetal egg and is present in the body only during pregnancy (by the way, it is on its determination in the urine that the well-known instant pregnancy test is based). The content and during a healthy pregnancy is clearly correlated with the timing. It is worth noting that this is far from a routine method that requires a lot of time and money and is used mainly for medical reasons.

It is impossible not to mention that finding out the gestational age, calculating and suggesting the probable age of the fetus is within the competence of the obstetrician when conducting a vaginal examination in the early stages. The main object of research in this case will be the uterus and palpation (manual) determination of its size. Of course, we are not talking about absolute accuracy, but the data obtained is quite enough to successfully monitor the health of the expectant mother and fetus.

What does "gestational" mean?

Many people hear this word for the first time in a antenatal clinic. The Latin gestatio literally translates as "bearing." Therefore, "gestational" means "pertaining to pregnancy."

Gestational age is calculated from the moment of conception. Determining exactly when this happened is extremely difficult. It may take up to several days for a fertilized egg to implant after intercourse. At the initial stage of embryo development, even a few hours play an important role. Therefore, the inaccuracy in the definition of the "starting point" leads to a relative conditionality of the calculation.

Gestational disc to determine due date

There are various calculators, the main purpose of which is to determine the date of birth of the baby. Gestational circle is an indispensable tool for preparing for childbirth and better control of the pregnancy process. With its help, every woman can determine the "X date" at home. This is necessary, since premature and late births pose the same danger. Therefore, it is important to calculate the expected day of delivery and, as it approaches, carefully monitor the signals of the body.

Statistics say that about 2% of babies are born on exactly the calculated day. The date that the calculator will show is better considered conditional. Most likely, the baby will be born a few days earlier or later. Normal childbirth is considered between 38 and 40 weeks. But each organism has its own unique features. Some women live up to 42 weeks, in which case maximum attention from doctors is required.

Gestational cycle is one of the most informative calculators. In addition to the estimated date of birth, it can be used to determine the height and weight of the embryo as it develops. In addition, many parents are interested in what sign of the zodiac and in the year of which animal according to the eastern calendar a child will be born. For some couples, it helps to choose a name.

How the gestational cycle works

With this visual calculator, it is easy to determine the date of delivery and track the growth and weight of the fetus during pregnancy. The outer disk is divided into 12 months. Each day corresponds to one division on the scale. For convenience, long marks are indicated every 5 days.

Numbers 1-40 on the moving part of the disc correspond to weeks of pregnancy. Also, using a background with different saturation, trimesters are highlighted: the first - from to , the second - from to , the third - from to . Closer to the center is the scale of weight, and at the last level - the growth of the fetus.

There are 3 arrows on the circle: green thin (first day of the last menstruation), EDD (estimated date of delivery) and a static “today”. In the center of the circle, basic information is displayed: the beginning of the last menstruation, the expected date of birth and the baby's zodiac sign. In the area under the disk, the number of weeks and days before childbirth is instantly calculated, as well as zodiac characteristics.

How to determine the gestational age using a gestational disc

Many obstetrician-gynecologists in different countries, including Russia, use the gestational circle. The simplicity of the method allows it to be used by absolutely every woman.

When planning a pregnancy, it is especially important to keep a menstrual calendar. This will help to determine the expected date of birth as accurately as possible. To calculate the gestational age according to the gestational circle, it is enough to move the thin green arrow to the date of the start of the last menstruation. The PDR arrow will indicate the date of delivery, provided that the pregnancy ends at 40 weeks. Using the “today” arrow, it is easy to track the average height and weight of the fetus for each week.

For example, the last period was from 12 to 16 December. For the calculation of the gestational circle, only the first date is important - December 12. Set the thin green arrow to this number. Twisting the arrow, pay attention to the center of the circle. This is much more convenient than peering into divisions. The “today” arrow indicates that the woman is at the beginning of the 8th week of pregnancy, the fetus has grown to 18 mm and weighs 1 g. You need to prepare for childbirth within 1-2 weeks from September 18th.

What should a woman do if she doesn't know her last menstrual period?

In this case, the gestational cycle will be ineffective for determining the date of birth of the child on your own. Usually, doctors prescribe a blood test for hCG. Chorionic gonadotropin is a hormone that is released in the body of a woman after implantation of the embryo in the uterus at 4 obstetric weeks. From this point on, you can get the most reliable results.

When using the strip test at home, the second strip may be translucent. This indicates either the unsuitability of the test, or a small amount of the hCG hormone in the body. To obtain reliable results, you need to try again in a week if menstruation does not begin. A weakly pronounced second strip can appear in women taking hormonal drugs, regardless of pregnancy.

Home test only shows pregnancy. According to the result of a biochemical blood test, its duration is determined. Don't put off checking. Analysis for hCG is most reliable in the first 12 weeks. Gradually, the level of the hormone decreases, and at a later date it is difficult to determine the time of conception.

When the week of pregnancy is known, the gestational circle can be used to calculate the date of delivery and determine the size of the fetus. To do this, just set the “today” arrow to the mark corresponding to the current date.

For example, it's week 9. At this stage of development, the embryo has reached 23 mm and weighs 2 g. The expected date of birth is September 9. The green arrow indicates the approximate date of the last menstrual period.

Errors

Bearing a fetus is a complex process that every woman proceeds in a special way. Moreover, the course of the first pregnancy does not mean that the next ones will follow the same scenario.

The pregnancy calculator is subject to certain errors. In addition, when setting the initial data, errors are not ruled out. The accuracy of the calculation depends on the individual characteristics of the organism. The pregnancy wheel shows the most accurate result with a standard menstrual cycle of 28 days. If the duration is longer, for example, 35 days, then ovulation will occur on average on the 21st day. This leads to an increase in the difference between obstetric and embryonic terms.

In addition, the error can be caused by inaccuracy in determining the embryonic period. The spermatozoon is able to remain in the female body for up to 3 days. Fertilization can occur at any time. Taking into account all factors, including the individual characteristics of the body of the expectant mother, the error in calculating the expected date of birth often reaches 2 weeks. Ultrasound gives more accurate results, although the method of calculating the beginning of the last menstruation is recognized worldwide as one of the best.

Why in the first two weeks the height and weight on the disk are zero

You can see that in the first two weeks the figures are zero. However, this period is part of the entire pregnancy cycle. The fetus in the womb develops surprisingly quickly. Therefore, in determining the date of birth, every day is important. At the same time, there are different terms - obstetric and embryonic, which are important not to be confused.

Some mistakenly believe that the first week is counted from the moment of conception. In fact, pregnancy begins on the last day of the menstrual cycle. Directly during this period, the birth of a new life could not occur. The moment of conception depends on ovulation and varies within a couple of weeks.

With a standard menstrual cycle of 28 days, ovulation occurs on the 14th day. In this case, the embryonic period will lag behind the obstetric period by about 2 weeks. In practice, this means that at the end of the first month of pregnancy, the actual age of the embryo is only 2 weeks.

Why sometimes the calculations by different methods do not match

Many women are surprised to find that the dates of birth according to different calculations do not match. Which one to believe?

In official medicine, embryos develop in the same way during the first trimester. On ultrasound, the gestational age is determined according to the table of correspondence between the size of the fetus and a certain period of development. For example, the calculation for the last menstruation shows the result of 12 weeks, and the diagnostician calls 11 weeks. More reliable is considered to be the period set during the first ultrasound. In this example, the difference is due to early ovulation, but it can be late. For the doctor, the result of an ultrasound examination is a priority.

During the second and third trimesters, each fetus develops at its own pace. Therefore, the data from the averaged tables may not fully correspond to reality. Deviations within one week are considered normal. In the ultrasound protocol, the specialist indicates what period the development of the fetus corresponds to.

The gestational cycle gives an idea of how the unborn child develops every day. At the beginning of the first trimester, the embryo gains only a couple of grams every week, but the difference, for example, between and 21 weeks is an average of 71 g. It is interesting for every woman to know how the fetus changes. With the gestational circle, observation becomes simple and even more fun.

The most important weeks of pregnancy

In order for the fetus to develop correctly and the baby is born healthy, the fact of pregnancy must be established as early as possible. It is not at all necessary that the expectant mother will intuitively feel the conception, or from the first weeks there will be obvious signs in the form of a heightened sense of smell, morning sickness, etc. It is not uncommon for a woman to find out about pregnancy only by her enlarged belly.

The following factors are of particular danger to pregnant women:

Unhealthy habits.
Stress.
Unbalanced diet, deficiency of nutrients (mainly iron and folic acid).
Great physical activity.
Overheating or undercooling.
Taking medications incompatible with pregnancy.
Infectious and inflammatory diseases.

It is necessary to prepare the body in advance for pregnancy in order to minimize the risks for the fetus and the expectant mother. But even if everything goes according to plan, there are times when extra care must be taken. If at any stage of pregnancy a woman feels severe discomfort, burning, or even unreasonable anxiety, you should visit a doctor.

When to be especially careful

Critical periods coincide with phases of active growth of the embryo and placenta. The following are considered the most dangerous weeks:

I trimester - 2-3, 4-7, 8-12.
II trimester - 18-22.
III trimester - 28-32.

The insidiousness of the first weeks lies in the fact that a woman may not know about pregnancy. As a result, the prerequisites are not met. From 4 weeks, the main organs are formed. During this period, it is especially important to follow the doctor's instructions in order to prevent pathologies. At the last critical stage of the first trimester, the placenta is formed - a natural shield that will increase with the fetus.

The period from to 22 weeks is considered the most important. At this time, the unborn baby is most active. The biggest risks to the life of the fetus and the health of the woman are sexually transmitted infections. One of the main conditions is to use barrier protection during sexual intercourse.

By the beginning of the third trimester, the fetus resembles a baby as much as possible, but it is not yet able to survive separately from the mother's body. Causes of preterm labor may include placental abruption, infections, and isthmic-cervical insufficiency. To prevent this, you need to follow absolutely all the doctor's instructions, take care of your own health and eliminate stress.

There are no critical periods on the gestational cycle. This is due to the fact that they do not have to be difficult at all. The more you focus on the dangers, the stronger the destructive effect of stress. You can use the pregnancy wheel during the entire period of gestation. On the diagram, it is convenient to track the transition to a new trimester, the stages passed and the approaching date of birth.

Description

Universal pregnancy calculator is a convenient and practical tool for calculating a number of parameters that are important and interesting for the expectant mother. The calculator is a circle, similar to a watch dial, the inside of which can be rotated, setting one or another hand in the desired position. For example, by setting a thin green arrow so that it points to the first day of the last menstruation, you will determine the date of future births by the arrow "PDR", and by the arrow "today" you will find out what week of pregnancy you are now, and what is the height and weight of the fetus on present day. The Pregnancy Wheel can also be used in other ways. For example, if the birth has already taken place, then you can set the arrow "Ed" (estimated date of birth) so that it points to the day of delivery. Then a thin green arrow will show you the date on which you had your last period before pregnancy. Among other things, the calculator determines the zodiac sign of the unborn child, and even his zodiac animal according to the eastern calendar.

Online pregnancy calculator will help you calculate the duration of pregnancy, determine the expected date of delivery, calculate the age of the fetus, find out when the end of the first and second trimester will come. The pregnancy calculator is a free service. Depending on the individuality of the organism, some data may not match.

Every pregnant woman keeps her own calendar, where she writes down all the changes that occur to her during pregnancy. However, the modern pace, a lot of family concerns do not always allow you to track on your own what week of pregnancy is going on and how the baby should develop. A pregnancy calendar comes to the aid of busy mothers: this is a complete description of all the changes that are happening at this stage with mom and baby. Thanks to this, a woman can easily track how much the baby weighs, what she should feel, what problems await her. But in order to find out how the child develops, you need to determine what the woman's gestational age is.

First day of last menstrual period:

1 2 3 four 5 6 7 eight 9 ten eleven 12 13 fourteen fifteen 16 17 eighteen 19 twenty 21 22 23 24 25 26 27 28 29 thirty 31 January February March April May June July August September October November December 2018 2019 2020

Average cycle time (days):

22 23 24 25 26 27 28 29 thirty 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45

Calculation results

- Estimated date of conception

- Age of the fetus

- Pregnancy age

How to find out the time of conception?

Traditionally, in order to determine what is the current gestational age, a woman comes to the antenatal clinic in the clinic. The doctor conducts an examination, if necessary, prescribes an ultrasound and focuses on the last menstruation in the setting of the term. Based on this date, a calculation is being made when the mother should give birth.

But women should be warned that this calculation will not always tell you the exact day of delivery. In medicine, there are two terms for determining pregnancy: obstetric and real. What is their difference?

OB term helps you determine when your pregnancy started based on the date of your last period. In this case, the date of conception is not taken into account, since it is unknown to the doctor. The doctor proceeds from the concept of a woman's standard menstrual cycle, which lasts 28 days. Therefore, conception could occur during ovulation on the 14th day after the start of the cycle. It turns out the difference between the obstetric period and the embryonic period by 2 or even 3 weeks.

You can find out the actual term more precisely if you undergo an ultrasound scan. However, ultrasound is prescribed no earlier than 10-12 obstetric weeks, and the woman's curiosity is much stronger.

How can you find out your own gestational age so that you can refer to the calendar later?

To do this, it is desirable to know the date of conception, or at least the possible days when this could happen. If you cannot set the date, you can use reusable pregnancy tests. The devices are equipped with sensors that determine the gestational age. The error of such devices is small.

You can also calculate the gestational age yourself, based on the obstetric calculation method. But if this is difficult for you, an online calculator will come to the rescue. This is a program on the site that will calculate the approximate date of your ovulation and, therefore, the expected date of conception.

How does the calculator work and what is needed for it? You just need to enter the first and last date of your period. The online calculator itself will calculate the middle of the term and determine the date of conception of your child.

If you know the date of conception, an online calculator will also help you determine the time when pregnancy occurred. The way it works will be different. You need to enter the date of conception into the calculator, and it will calculate the gestational age by week. So you will know exactly which week goes on what dates you have, and you will be able to observe from the descriptions how your child grows.

When is the due date?

Now is the time to find out the due date. The same calculator that determined the date of conception will help you calculate the date of birth. The online calculation is based on the data on the date of conception or the last menstruation. In the latter case, you will know the due date based on the obstetric term.

If you know exactly how many weeks you have, then you can guess when to expect the start of labor. This usually happens at 38-40 weeks. Some women live up to 42 weeks: such a pregnancy is not considered post-term. It should also be noted that an error could occur when determining the gestational age. An online calculator can also make a mistake, as it calculates based on generally established observations. In addition, you could enter inaccurate data into it.

Practice shows that the date of delivery is the date of the beginning of the last menstruation, to which 9 months are added. In these numbers, we should expect the completion of the family. But what to do if it is not possible to determine the period by menstruation, since the woman no longer remembers the exact date?

HCG analysis

If a woman does not follow the regularity of the cycle and does not remember the date of the last menstruation, the calendar is unlikely to help here. In this case, doctors recommend doing a blood test for hCG, a hormone that allows you to determine the presence of pregnancy even in the early stages.

HCG (human chorionic gonadotropin) is produced in a woman only during pregnancy with a fetal egg. A biochemical blood test is able to determine its amount in the body and, on the basis of this, establish the presence and duration of pregnancy. The most informative are the first 12 weeks of pregnancy, when the level of hCG is still high. Gradually, it begins to decline, and a blood test will no longer give reliable data.

Approximately determine the size of the fetal egg, and according to it - what is the current gestational age, the doctor will be able to examine the vagina and palpation.

Why do I need to know the exact date?

Not all women are attentive to their pregnancy and calculate the period by weeks. They think that it is the task of the doctor to calculate the gestational age in order to subsequently calculate the date of birth. During pregnancy, they do not think about how many weeks they have now, and how the baby should develop.

In vain, because no one better than the mother herself can determine whether the baby is comfortable inside. Dangers lie in wait for a pregnant woman at every turn, and it is better if she knows her due date by weeks. A calculator and a calendar can help with this, so it is not necessary to ask a doctor every time.

If you don't know how many weeks of pregnancy you have, open the calculator on the site, enter the required data and you will receive an answer. It will help you remember the doctor's recommendations and warn yourself and your baby against possible complications. Isn't it nice to see in the photo and video how your baby is growing week by week? After all, you can only look inside with the help of ultrasound, but this happens only three times during the entire pregnancy.

The need to undergo screenings is another reason why a woman needs to know the exact gestational age. Studies, including a blood test for genetics and ultrasound, take place within strictly defined terms. If you do the analysis sooner or later, you can get an inaccurate answer.

Do not neglect the calculation of the gestational age by weeks. This will give the woman valuable material to determine if the baby is developing according to the norm, if there are any deviations, and what studies still need to be done.

What errors are possible?

Unfortunately, if the exact date of conception is not known, any weekly pregnancy calendar or conception calculator may not be accurate. The baby development calendar is based on the data that was originally determined. What if they are incorrect?

Unfortunately, errors cannot be avoided. According to statistics, in almost 20% of women during pregnancy, the difference between obstetric and embryonic terms is 14 days. If a woman's cycle is long, such as 35 days instead of 28 days, ovulation may only occur on day 21. Consequently, the difference between the obstetric term and the real one will be even greater. 1 week of the embryonic period will be equal to 5 or 6 obstetric weeks.

But even in the formulation of the embryonic period there is an error. It is several days, since the sperm can be stored in a woman's body for 3 days, so fertilization could not occur on the day of ovulation, but later.

Calculating the gestational age is a painstaking task.
