If you are trying to become pregnant, your chances will be improved if you have sex at a particular time of your cycle. Knowing when you ovulate – when an egg is released from your ovaries – is the key to knowing when that right time is.

When you are most fertile

The 5 days before ovulation, together with the day you ovulate, are the days when you are most likely to conceive. Sperm can live up to 5 days inside your body, so if you have sex up to 5 days before your egg is released, you can get pregnant. After ovulation, though, your egg can only live for 12 to 24 hours. After this time is up, your time for getting pregnant has gone for now till the following month.

Your chances of getting pregnant are at their highest in the 3 days leading up to and including ovulation.

Predicting ovulation

Ovulation usually happens about halfway through your menstrual cycle, about 14 days before the first day of your next period, but the exact time can vary. Although signs that you are about to ovulate can be subtle, there are some things you can pay attention to and track over time to help you predict your fertile window.

Changes in mucus

Noticing how your vaginal secretions change during your menstrual cycle is the basis of the Billings ovulation method. Around the time of ovulation, you may notice your secretion is clear, stretchy and slippery — similar to egg whites. After ovulation, when the chances of becoming pregnant drop, the secretion tends to become cloudy and thick, or disappear entirely.

Changes in body temperature

When you’ve just ovulated, your body temperature may increase very slightly, by about half a degree Celsius. If you’re using temperature as a means of keeping track of when you are most fertile, you need to use a special thermometer to take your temperature every morning before you get out of bed. If you record the readings every day using a graph or a spreadsheet, it’s possible to learn your pattern over time. The time when you are most fertile is 2 to 3 days before the rise in temperature.

Other signs

There may be other signs that you are near the time of ovulation, such as mild abdominal cramps, breast tenderness or increased sex drive. However, using these signs to predict when you’re fertile is not the most reliable method.

Using ovulation calculators and kits

Ovulation calendars and kits can also help you predict ovulation.

Ovulation calendars are available on websites such as www.yourfertility.org.au, and use the date of your last period and the length of your cycle to predict when you are likely to be most fertile.

Home ovulation predictor kits are available from pharmacies. You use the kit a few days before your predicted ovulation day, to test for a rise in the level of a hormone called luteinising hormone (LH) in your urine. A positive result indicates you will ovulate within the next 24 to 36 hours.

A blood test, which your doctor can order, can also detect ovulation by measuring levels of the hormone progesterone.

If you are trying to get pregnant, there are also a number of other things you should consider, such as taking folate, maintaining a healthy diet and making sure your vaccinations are up to date.

How many days after ovulation can you get pregnant?

It is possible to become pregnant after ovulation. When a person has sex within 12–24 hours after the release of a mature egg, there is a high chance of conceiving.

Ovulation occurs when one of the ovaries releases a mature egg. This is the time when the body is ready to receive sperm for fertilization.

If fertilization does not occur, the egg disintegrates into the uterine lining. The body will then shed the remains during a person’s monthly period.

Ovulation lasts anywhere from 12–24 hours. After the ovary releases an egg, it survives for about 24 hours before it dies, unless a sperm fertilizes it.

If a person has sex days before or during the ovulation period, there is a high chance of conceiving. This is because sperm can survive up to 5 days in the cervix. Therefore, it is important to understand the fertile window.

The fertile window is the period of time during which it is possible to become pregnant from sex. This is the day of ovulation plus the amount of time that sperm can live inside the cervix before it fertilizes the egg.

According to the American College of Obstetricians and Gynecologists (ACOG), a person can become pregnant if they have sex anywhere from 5 days before until 1 day after ovulation.

Depending on the menstrual cycle, the fertile window may vary from one person to another.

To calculate the fertility window, a person should note the first day of a period until the next period occurs. This timeframe is the menstrual cycle. On average, most people who menstruate have a 28-day cycle.

However, according to the Office on Women’s Health, for some, it may last 21–35 days.

According to the ACOG, ovulation occurs around day 14 of the menstrual cycle.

A person with a 28-day cycle, for example, will have their fertile window 5 days before the ovulation date.

Pregnancy is possible 12–24 hours after ovulation. This is because the released egg can only survive 24 hours before the sperm can no longer fertilize it.

The likelihood of getting pregnant on the days before and after ovulation varies from one person to another.

An older study from 1995 looked at the timing of sexual intercourse in relation to ovulation and the likelihood of conception.

Out of 221 healthy women, there were 192 pregnancies. Researchers concluded they could estimate the odds of becoming pregnant on each day of the fertile window as between 10–33%, depending on the day.

5 days before ovulation	10%
4 days before ovulation	16%
3 days before ovulation	14%
2 days before ovulation	27%
1 day before ovulation	31%
Ovulation day	33%

The same study authors also note there could be a 12% chance of conceiving on either day 7 before ovulation and the day after ovulation.

However, the chances of becoming pregnant before or after ovulation depend on several factors, including:

age
frequency of sexual intercourse
menstrual cycle

For those trying to conceive, tracking ovulation is crucial to ensure they identify the most fertile days in the menstrual cycle.

Here are some of the methods a person can use to track or predict ovulation.

Basal body temperature charting

Basal body temperature (BBT) is the temperature when the body is at rest.

Charting BBT for a series of months by measuring every morning after waking up will help predict ovulation.

During or when ovulation approaches, there is a slight increase in BBT. A person can use a digital thermometer to track these small changes in temperature.

Monitoring BBT can help tell when ovulation occurs and therefore predict the days in the cycle when pregnancy is possible.

Ovulation predictor kits

Using ovulation predictor kits, such as test strips and digital tests, will help measure the level of luteinizing hormone (LH), which usually rises during ovulation.

A person needs to take tests for consecutive days to detect the rise in LH.

Once they notice a consistent rise, experts recommend having sex daily for the next couple of days to increase the chances of pregnancy.

Cycle charting apps

Several cycle apps, such as the Clue period tracker and Flo period ovulation tracker, can help calculate the ovulation period and fertile window.

Charting ovulation using these apps will indicate the ovulation date and days when a person’s body is most fertile.

Fertility monitors

For people trying to conceive or wishing to avoid pregnancy, using fertility monitors to track ovulation can help people plan intercourse.

Fertility monitors work by measuring significant body changes, such as BBT, heart rate, and breathing.

By compiling this data, the fertility monitor can predict the fertile window.

Cervical mucus method

Observing cervical mucus can give an idea of when a person may be ovulating.

When ovulation approaches, the cervical mucus changes to a thin, clear, stringy, slippery consistency. It may look similar to raw egg whites.

The mucus allows the sperm to swim to the released egg during intercourse.

Ideally, this is the ideal time to have sex due to the high chances of becoming pregnant.

Watching ovulation signs, such as a slight increase in BBT, changes in cervical mucus, and increased sex drive, can help determine the best time to have sex to boost chances of becoming pregnant.

In addition, having sex during the fertile window increases the chances of conception. During this timeframe, the body is ready to receive sperm for fertilization.

On average, a menstrual cycle lasts between 21–35 days.

An irregular cycle or absent cycle that lasts fewer than 21 days or more than 35 days, can mean that a person is not ovulating.

A person should speak with a doctor if they do not become pregnant after 1 year of trying to conceive.

Age may also determine when to seek help. People between 35–40 years of age should speak with a doctor after 6 months of trying to get pregnant. For those above 40 years of age, a healthcare professional may run some fertility tests.

A doctor may also test for possible signs of infertility or if a person has ever had repeated miscarriages, pelvic inflammatory disease, endometriosis, prior cancer treatment, or a history of irregular periods.

A person can get pregnant 12–24 hours after ovulation, as a released egg can survive up to 24 hours within the cervix.

For those trying to conceive, it is crucial to understand the menstrual cycle.

Beyond this, a person can use methods, such as BBT charting, cycle charting apps, fertility monitors, changes in cervical mucus, and ovulation predictor kits to boost the chances of pregnancy.

Fomin's clinic — a network of multidisciplinary clinics

Today's world is full of information: literally with one click, each of us can open the Universe and learn everything - from string theory to concert posters for the next week. It is all the more interesting that, having unlimited access to knowledge, we still live in myths - and sometimes they arise, including thanks to the Internet, replicating untruth and absurdity.

We have prepared for you a short “blitz” of six questions or myths about pregnancy and conception, so that you are fully equipped and do not believe the tales on the Internet.

Well... not exactly. Firstly, the idea of a “full examination” is a clear exaggeration, because there is no single list of tests that an expectant mother needs to pass. Ideally, visit a doctor three months before the end of contraception, get tested for STIs and antibodies to rubella. If additional examinations are required, you will be individually prescribed everything you need - including, probably, vaccinations that should be “updated”. As for alcohol and smoking, they are really contraindicated at the stage of pregnancy planning, so if you have these addictions, you will have to give them up. However, it should be remembered that smoking cessation applies to both electronic cigarettes and “passive smoking”, which can lead to dangerous consequences for the fetus.

Spoiler: no big deal. Do not panic and blame yourself for all mortal sins because of a glass of wine. With the recognized insecurity of alcohol, scientists have proven that a woman drinking 1-2 servings a couple of times a week should not harm the unborn child. For men, the allowable figures are slightly higher - 3-4 doses of alcohol per week. The main thing is to know the measure and not to overdo it.

There is, of course, a simplified formula for calculating the estimated due date: plus 7 days and minus 3 months from the date of the last period, but to be honest, it doesn’t work like that: the fact is that it is very difficult to “program” pregnancy and make sure that the child is born when you want. If you have a plan and are going to stick to it, be prepared for the fact that things can go wrong, if only because:

the duration of pregnancy is not 40 weeks, but 37-42 weeks, which means that you can easily fall into a five-week “loop”, which will reduce the chances of fulfilling the plan to zero;

with regular sex, the probability of conception is not 1 time per month (exactly when you guessed it), but 1 time per year.

Nothing is impossible... However, it is worth clarifying the question a little: you can get pregnant only during ovulation (more precisely, shortly after it), but you can have sex, which will lead to a long-awaited pregnancy, on different days. Of course, on the days of menstruation, the probability is lower than on the days that precede ovulation, but on none of the days of the menstrual cycle this probability is not zero.

Let's just say that trying multiple times a day is a bad idea. Why? At least because ejaculation more than once a day worsens the quality of sperm, as a maximum - such perseverance and zeal can create tension in the relationship of partners. Doctors advise to have sex every 2-3 days throughout the cycle, and not try to guess the moment and throw all your strength into this short period.

Planning the sex of a child is an extremely prolific topic for myth-makers. Some believe that with the help of a special table that takes into account such indicators as the age of the father and mother, the month of conception, it is possible to accurately calculate the sex of the child. This "method" is anti-scientific and has nothing to do with reality.

Another myth is that you have to get pregnant on the day you ovulate to have a boy. Previously, scientists really believed that X and Y spermatozoa differ from each other (Y are faster), and the sex of the child is formed due to the first one that broke through the defenses of the female egg. If you want to conceive a boy, you need to have sex on the day of ovulation so that the Y-sperms responsible for the "male sex" have more time to get to the egg located farthest from the entrance to the uterus.

However, this myth does not stand up to criticism: the fact is that there is no difference between the X and Y chromosomes, which means that the sex of the child does not depend on which of the sperm reaches the egg first. Moreover, not the fastest fertilizes the egg: thousands of spermatozoa simultaneously break its shell.

From this follows the conclusion: modern science does not know how to determine the sex of the child during natural conception, and therefore there is no universal recipe.

ᐈ Why can't get pregnant - Reproductive medicine, gynecology, pregnancy monitoring, urology

At a certain moment in life, we feel an irresistible desire to become the parents of our baby. For some couples, this happens immediately, while others plan to continue the family for a certain period of life.

What if after a while pregnancy does not occur? Women begin to worry, and a question or even a problem arises - “I can’t get pregnant, what should I do?”. First, figure out if you are doing everything right.

First of all, it is extremely difficult to conceive the first time. To get pregnant, you need to have regular sex without using contraceptives. Secondly, this should be done on time, or rather, on the days of ovulation (fertile period).

Reasons why you can't get pregnant

Ovulation is the process of release of an egg from the ovary. The menstrual cycle of a woman can theoretically be divided into 2 phases. In the first phase, in one of the ovaries (less often in both), the follicle grows and the egg matures in it. Around the middle of the cycle, the follicle ruptures and the egg is released - this is ovulation.

The ovum released from the follicle is ready for fertilization. Moving, she enters the fallopian tubes, where she meets with the sperm. The fertilized egg descends into the uterine cavity, where it is implanted, and pregnancy begins to develop. If fertilization does not occur or the fertilized egg is not implanted in the uterine cavity, then menstruation begins.

The probability of conception is maximum on the day of ovulation, and is approximately 33%. If we take into account that the average lifespan of a sperm cell is 2-3 days (in rare cases it reaches 5-7 days), and the egg remains viable for up to 48 hours, then the maximum duration of the "fertile period" is 7-9days (6-7 days before ovulation and 1-2 days after ovulation).

In the absence of ovulation, the egg does not mature or does not leave the follicle, which means that the spermatozoon has nothing to fertilize, and the onset of pregnancy in this case is impossible.

Lack of ovulation is a common cause of infertility in women who confess “I can’t get pregnant” at the appointment.

When planning pregnancy and simply for diagnosing women's health, determining the presence of ovulation is a top priority. There are several methods, including those that can be used at home.

How to determine ovulation?

Subjective feelings. Ovulation is usually not accompanied by any pronounced signs, and it can only be determined by carefully observing yourself. What to do and what to pay attention to?

About imminent ovulation says:

increased vaginal discharge in the middle of the menstrual cycle;
change in their color and consistency;
pain in the lower abdomen on the side where ovulation occurred.
Severe pain during ovulation occurs with a pronounced adhesive process or polycystic ovary syndrome.

Basal temperature measurement. Based on the temperature values in the rectum, a graph of basal temperature is plotted. On the days of ovulation, the temperature drops sharply, and then rises and stays at this level for 12-14 days, decreasing 1-2 days before the onset of menstruation.

An easier and more convenient method of determining ovulation at home are ovulation tests. They are similar to pregnancy tests, but are carried out approximately in the middle of the cycle and reliably show ovulation. If within three menstrual cycles, ovulation tests are negative, then you need to consult a doctor to find out the reasons for its absence.

The most reliable method for diagnosing ovulation is the ultrasound method (foliculometry). This requires repeated ultrasound monitoring. The study is safe, it can be done several times a year.

Why is there no ovulation?

There are many reasons why couples wonder why they can't get pregnant. Possible reasons for the lack of ovulation:

diabetes mellitus;
hyperprolactinemia;
diseases of the thyroid gland;
polycystic ovary syndrome;
hypothalamic-pituitary insufficiency;
metabolic disorders (obesity or underweight), etc.

Most often, the absence of ovulation occurs in polycystic ovary syndrome. Couples for 2 years can wait for conception, but they never will. The lack of ovulation can be corrected by hormonal stimulation of the ovaries, after which pregnancy will occur naturally.

If pregnancy does not occur in the natural cycle with ovarian stimulation, then intrauterine insemination is necessary. If, after insemination with polycystic ovary syndrome, pregnancy does not occur, then in vitro fertilization is indicated.

Obstruction of the fallopian tubes

As mentioned above, the egg and sperm meet in the fallopian tube, where fertilization takes place, and then the fertilized egg, moving through the fallopian tube, enters the uterus. Therefore, the next reason for the absence of pregnancy may be a violation of the patency of the fallopian tubes, which occurs due to previous inflammatory diseases and adhesions formed.

Tubal patency can be checked using hysterosalpingography and laparoscopy. If the obstruction of the fallopian tubes is confirmed, the patency of the tubes can be restored with the help of microsurgery. If it is not possible to restore the patency of the fallopian tubes, then the patient is recommended in vitro fertilization.

Pathology of the uterine cavity

Pathology of the uterine cavity can also be one of the reasons for the absence of pregnancy. These can be both congenital pathologies (absence or underdevelopment of the uterus, doubling, saddle uterus, septum in the uterine cavity), and acquired (scars in the uterus, intrauterine adhesions, uterine fibroids, endometrial polyp).

Methods for diagnosing uterine pathology are ultrasound and diagnostic hysteroscopy. For the treatment of uterine pathology, reconstructive surgery is sometimes necessary, and sometimes hysteroscopy is indicated.
