Your Body throughout Pregnancy

Your Body Before Pregnancy

Your Body Before Pregnancy

Before pregnancy, most of the space in your abdomen is taken up by the large and small intestines. There is no real separation between the areas of your pelvis and abdomen.

In the picture here, you can see that the vagina is behind the bladder (sac that collects urine) and urethra (tube for moving urine out of bladder and body). In its normal position, your uterus is above and behind the bladder, with the cervix protruding into the vagina. The pelvic colon, rectum and anal canal are behind the vagina and uterus.

Your Body at 6-7 Weeks of Pregnancy

When you are between 6 and 7 weeks pregnant, you may be experiencing the early signs of pregnancy: your period has stopped and you may have nausea, breast tenderness and swelling, frequent urination and fatigue.

At this point, your uterus has begun to grow and become more egg-shaped. The pressure of the growing uterus on the bladder causes frequent urge to urinate.

In this image, you can see the beginnings of the placenta in the uterus. The embryo is about 1/4 inch to 1/2 inch long and weighs 1/1,000th of an ounce.

The embryo’s head is large in proportion to the rest of the body. The internal organs are forming and the heart has been beating since the end of the 4th week.

The embryo is floating in the amniotic sac. Buds for the arms and legs emerge in the 5th week and, by the 7th week, buds for fingers and toes also appear. The umbilical cord is lengthening and will continue to grow, allowing the fetus freedom to move. The 7th week represents a milestone in development: the embryo is now considered a fetus.

Your Body at 12 Weeks of Pregnancy

At the 12th week of pregnancy, the placenta is much larger. It now produces the hormones needed to sustain the pregnancy. Your uterus is the size of a grapefruit and completely fills the pelvis. It rises up into the area of the abdomen, as shown in the image. The fundus, the upper end of the uterus, is just above the top of the symphysis where the pubic bones join together. This upward growth of the uterus takes pressure off the bladder and decreases the need for frequent urination. The mucus plug, a barrier to protect the growing fetus, fills your cervical canal.

The fetus is now about 3 inches long and weighs about 1 ounce. By this week, the fetus has fingernails and toenails and can open and close the fingers. The fetus will start to move, but you will not feel it yet.

Your Body at 20 Weeks of Pregnancy

Your Body at 20 Weeks of Pregnancy

By the 20th week of pregnancy, your uterus can be felt at the level of your belly button (umbilicus). The pelvic colon and small intestines are crowded upward and backward. The ascending and descending colon maintain their usual positions.

At this point, your uterus is especially enlarged where the placenta attaches to it (usually on the front or back wall). This gives the uterus an uneven bulge. The wall of the uterus, which lengthens and thickens early in pregnancy, stretches as the fetus grows, and becomes thinner now – just 3 to 5 millimeters thick. Your bladder moves up but not as much as your uterus, which straightens as it moves up.

As your uterus moves up, it rests against the lower portion of the front of your abdominal wall, causing it to bulge forward noticeably by your 20th week. The size of the bulge depends on how strong your abdominal muscles are. If they are firm, the uterus may be pressed against the spinal column, and there will be no noticeable bulge; if they are weak, the pressure of the uterus against the inside wall makes a sizeable bulge.

At this point, you should be able to feel light movements of the fetus. This is called “quickening.” You may recognize this earlier if you have been pregnant before. The fetus sleeps and wakes at regular intervals, is more active, is about 9 inches long and weighs between a half-pound and a pound.

At this point in pregnancy, the top of your uterus is about one-third of the distance between the bellybutton and the xiphoid cartilage at the lower end of your breastbone. Constipation is common because your uterus is pressing on your lower colon and hormones slow down your body’s excretion process. Between the growth of your uterus and general weight gain, you may be feeling fatigued. Some women also experience heartburn as your uterus presses against your stomach.

Your breasts are also changing to get ready for breastfeeding. First colostrum and then milk are produced by the grape-like clusters of tiny sacs (alveoli) deep within the breast tissue. Clusters of alveoli form lobules, which come together to form 15 to 20 lobes. Each lobe connects to a lactiferous duct for conveying milk. As the ducts extend toward the nipple and areola (darker area around the nipple), they widen into the lactiferous sinuses. These sinuses (or milk pools) release the milk through 15 to 20 tiny nipple openings in each breast when the baby nurses.

At week 28, the fetus is about 16 inches long and weighs two to three pounds. The skin is wrinkled but will become less so as more fat builds up under the skin in the next few weeks. Fine, downy hair called lanugo, and a waxy white protective substance covering the skin called vernix, are on the fetus’ body. Its eyes are open, and eyebrows and eyelashes were formed in the fourth month. The fetus sucks its thumb and its taste buds have developed. It kicks, stretches and moves frequently in your uterus—you’ll feel it moving around and others might even be able to see these movements!

Fetal organs and systems are quite well developed by the 28th week of pregnancy, but the final two months of gestation are important for further maturation of all body systems and organs.

Your Body at 36 Weeks of Pregnancy

Your Body at 36 Weeks of Pregnancy

By the end of the 36th week of pregnancy, your enlarged uterus almost fills the space within your abdomen. The fetus is inside the membrane sac within the uterus and high within the abdomen. The muscles of your abdomen support much of its weight.

During this week, the top of the uterus is at the tip of the xiphoid cartilage at the lower end of the breastbone, which is pushed forward.

The change in the position of the heart and the upward pressure of the diaphragm may make it hard to breathe at this point. The crowding of your stomach and intestines may contribute to discomfort after eating.

Your cervix is long, thick and filled with the mucous plug. By the 36th week, your vagina and urethra are elongated and all the tissues in the perineum (area between vaginal and anal openings) are enlarged. The swollen perineum projects outward in the last weeks of pregnancy and readily expands during labor.

The brain of the fetus is growing rapidly, but bones in the skull are soft so that he or she will fit through your vagina at birth. The lungs are still forming. You will likely feel the fetus kicking and may be aware of rhythmic movements, which could be hiccups or thumb sucking. Another possible sensation, sudden movement, may be a startle response.

Your Body at 40 Weeks of Pregnancy (Internal)

Your Body at 40 Weeks of Pregnancy (Internal)

At full term, or 40 weeks of pregnancy, the fetus’ head has generally lowered into your pelvis, where it takes up most of the space. This is called “lightening.” In first pregnancies, this may happen a few weeks before labor. In repeat pregnancies, this can happen at the time of labor. The canal of the broad, enlarged cervix is still filled with the plug of mucous. If this is your first pregnancy, the small opening at the bottom of your cervix is usually not dilated, whereas if you have given birth before, it will often be open as wide as two fingers some time before labor begins.

At this point, you may be experiencing frequent urination, increased constipation, edema (water retention) and aching legs or vulva. Varicose veins in the vulva, rectum and legs are also possible. This is because of the position of the uterus, the pressure of the baby's head and a loss of muscle tone as the hormone relaxin loosens your tissues in preparation for birth. Other changes at this time include increased development of blood vessels and increased amount of blood.

Your Body at 40 Weeks of Pregnancy (External)

You can see that the round ligament is long and enlarged. It is also farther forward because of the twisting of the uterus. The enlarged uterosacral ligament is shown stretched taut by the enlarged uterus. Backaches in late pregnancy may be due to the stress of the weight of your uterus on the ligaments that connect it to your spine.

Because your uterus dropped a bit, you may be able to breathe and eat more comfortably near the end of your pregnancy.

At this time, the lungs of the fetus are likely fully mature and ready to begin breathing. The fetus gains about a half pound every week at the end of pregnancy, for a birth weight of roughly 7 pounds, and is growing longer for a birth length of about 18 to 21 inches.

Labor starting on its own around week 40 is a sign that your body is ready to give birth and your baby is ready to be born.

Changes in the cervix during pregnancy

Pregnancy is always pleasant, but sometimes not planned. And not all women have time to prepare for it, to be fully examined before its onset. And the detection of diseases of the cervix already during pregnancy can be an unpleasant discovery.

The cervix is ​​the lower segment of the uterus in the form of a cylinder or cone. In the center is the cervical canal, one end of which opens into the uterine cavity, and the other into the vagina. On average, the length of the cervix is ​​3–4 cm, the diameter is about 2.5 cm, and the cervical canal is closed. The cervix has two parts: lower and upper. The lower part is called the vaginal, because it protrudes into the vaginal cavity, and the upper part is supravaginal, because it is located above the vagina. The cervix is ​​connected to the vagina through the vaginal fornices. There is an anterior arch - short, posterior - deeper and two lateral ones. Inside the cervix passes the cervical canal, which opens into the uterine cavity with an internal pharynx, and is clogged with mucus from the side of the vagina. Mucus is normally impervious to infections and microbes, or to spermatozoa. But in the middle of the menstrual cycle, the mucus thins and becomes permeable to sperm.

Outside, the surface of the cervix has a pinkish tint, it is smooth and shiny, durable, and from the inside it is bright pink, velvety and loose.

The cervix during pregnancy is an important organ, both in anatomical and functional terms. It must be remembered that it promotes the process of fertilization, prevents infection from entering the uterine cavity and appendages, helps to "endure" the baby and participates in childbirth. That is why regular monitoring of the condition of the cervix during pregnancy is simply necessary.

During pregnancy, a number of physiological changes occur in this organ. For example, a short time after fertilization, its color changes: it becomes cyanotic. The reason for this is the extensive vascular network and its blood supply. Due to the action of estriol and progesterone, the tissue of the cervix becomes soft. During pregnancy, the cervical glands expand and become more branched.

Screening examination of the cervix during pregnancy includes: cytological examination, smears for flora and detection of infections. Cytological examination is often the first key step in the examination of the cervix, since it allows to detect very early pathological changes that occur at the cellular level, including in the absence of visible changes in the cervical epithelium. The examination is carried out to identify the pathology of the cervix and the selection of pregnant women who need a more in-depth examination and appropriate treatment in the postpartum period. When conducting a screening examination, in addition to a doctor's examination, a colposcopy may be recommended. As you know, the cervix is ​​covered with two types of epithelium: squamous stratified from the side of the vagina and single-layer cylindrical from the side of the cervical canal. Epithelial cells are constantly desquamated and end up in the lumen of the cervical canal and in the vagina. Their structural characteristics make it possible, when examined under a microscope, to distinguish healthy cells from atypical ones, including cancerous ones.

During pregnancy, in addition to physiological changes in the cervix, some borderline and pathological processes may occur.

Under the influence of hormonal changes that occur in a woman's body during the menstrual cycle, cyclic changes also occur in the cells of the epithelium of the cervical canal. During the period of ovulation, the secretion of mucus by the glands of the cervical canal increases, and its qualitative characteristics change. With injuries or inflammatory lesions, sometimes the glands of the cervix can become clogged, a secret accumulates in them and cysts form - Naboth follicles or Naboth gland cysts that have been asymptomatic for many years. Small cysts do not require any treatment. And pregnancy, as a rule, is not affected. Only large cysts that strongly deform the cervix and continue to grow may require opening and evacuation of the contents. However, this is very rare and usually requires monitoring during pregnancy.

Quite often, in pregnant women, during a mirror examination of the vaginal part, polyps cervix. The occurrence of polyps is most often associated with a chronic inflammatory process. As a result, a focal proliferation of the mucosa is formed, sometimes with the involvement of muscle tissue and the formation of a pedicle. They are mostly asymptomatic. Sometimes they are a source of blood discharge from the genital tract, more often of contact origin (after sexual intercourse or defecation). The size of the polyp is different - from millet grain rarely to the size of a walnut, their shape also varies. Polyps are single and multiple, their stalk is located either at the edge of the external pharynx, or goes deep into the cervical canal. Sometimes during pregnancy there is an increase in the size of the polyp, in some cases quite fast. Rarely, polyps first appear during pregnancy. The presence of a polyp is always a potential threat of miscarriage, primarily because it creates favorable conditions for ascending infection. Therefore, as a rule, more frequent monitoring of the cervix follows. The tendency to trauma, bleeding, the presence of signs of tissue necrosis and decay, as well as questionable secretions require special attention and control. Treatment of cervical polyps is only surgical and during pregnancy, in most cases, treatment is postponed until the postpartum period, since even large polyps do not interfere with childbirth.

The most common pathology of the cervix in women is erosion . Erosion is a defect in the mucous membrane. True erosion is not very common. The most common pseudo-erosion (ectopia) is a pathological lesion of the cervical mucosa, in which the usual flat stratified epithelium of the outer part of the cervix is ​​replaced by cylindrical cells from the cervical canal. Often this happens as a result of mechanical action: with frequent and rough sexual intercourse, desquamation of the stratified squamous epithelium occurs. Erosion is a multifactorial disease. The reasons may be:

• genital infections, vaginal dysbacteriosis and inflammatory diseases of the female genital area;
• is an early onset of sexual activity and a frequent change of sexual partners. The mucous membrane of the female genital organs finally matures by the age of 20-23. If an infection interferes with this delicate process, erosion is practically unavoidable;
• is an injury to the cervix. The main cause of such injuries is, of course, childbirth and abortion;
• hormonal disorders;
• , cervical pathology may also occur with a decrease in the protective functions of immunity.

The presence of erosion does not affect pregnancy in any way, as well as pregnancy on erosion. Treatment during pregnancy consists in the use of general and local anti-inflammatory drugs for inflammatory diseases of the vagina and cervix. And in most cases, just dynamic observation is enough. Surgical treatment is not carried out throughout the entire pregnancy, since the excess of risks and benefits is significant, and after treatment during childbirth, there may be problems with opening the cervix.

Almost all women with various diseases of the cervix safely bear and happily give birth to beautiful babies!

FIRST SIGNS OF PREGNANCY

All girls have heard about the first signs of pregnancy, the so-called discharge .

How else can you tell if you are pregnant or not? Let's say you had a long delay in your menstrual cycle. Time flies, and menstrual bleeding does not start. In this case, you will systematically feel nausea, while the mammary glands will seem heavy to you.

In addition to discharge, another sign of pregnancy is the constant thirst for sleep. The everyday activities of the people around you are annoying, and besides, you become very nervous about the presence of certain smells.

In addition to discharge, the first sign of pregnancy is an increase in appetite. Food begins to evaporate from your refrigerator at an astonishing rate and in a variety of combinations of ingredients. At the same time, saliva may still flow, and the number of midnight trips to the toilet will also increase. During the day, you can’t walk for a long time either, this is problematic because of the constant desire to urinate.

All of these discharges and other signs may be present both together and separately. Often a woman talks about a delay in the menstrual cycle in the absence of any deviations in her state of health.

There is an accessible and easy way to clarify these facts. Of course, no method will give you 100% guarantees. You can get a reliable 100% conclusion only after an examination by a gynecologist and a special diagnosis (examination). However, when the first signs of pregnancy appear (discharge, etc.) in the initial 10-12 days of the deviation of the menstrual cycle from the chronology, even in a good clinic you will not be able to guarantee the results of studies to determine pregnancy.

If menstruation does not start at the expected time, then after waiting for the morning, measure the body temperature in the rectum. An ordinary thermometer (medical, of course) is inserted into the rectum as soon as you wake up. Do not get out of bed while performing this operation. Doctors advise to prepare a thermometer in the evening and put it near the bed.

Need more than 6 hours of sleep. The thermometer is inserted behind the muscle that compresses the anus. The insertion depth of the thermometer is 2 centimeters, and the measurement time is from five to seven minutes. Record the measurement results. Measure body temperature every day for 7-10 days. If the temperature is most often more than 37 C, then this indicates the presence of the first signs of pregnancy.

In the absence of menstruation for 3 or more days, as well as in the presence of the first signs of pregnancy (discharge), gynecologists recommend doing a test to determine early pregnancy (most of the tests that are commercially available detect the presence of pregnancy already on the 1st day of delay !). They are easy to use and quite reliable.

The confidence probability of the test turns out to be much greater if it is carried out two or three times.

Outwardly, these tests are all different, but they are based on one chemical reaction to a specific hormone called human chorionic gonadotropin. This hormone is produced during pregnancy. The breakdown products of the hormone are excreted in the urine. The chemical reagent that drinks the dough plate interacts with these products.

Check that the test has not expired. For the experiment, the purpose of which are the first signs of pregnancy (discharge, etc.) it is better to use morning urine. After sleep, the content of the hormone and its decay products in the female body increases. This means that the probability that the tester will detect this increases. If you are a person who does not trust such tests, then as an option you can do a urine test to quantify the content of hCG. Although, this analysis is carried out by far not every medical and diagnostic center.

Suppose 3-4 weeks have passed, the temperature in the rectum is systematically over 37 degrees, and the test for determining signs of pregnancy gave a positive result 2 times. At the same time, you feel great, there are no subjective disorders and you are full of energy. There may even be an emotional upsurge. Do you need a women's consultation to determine the first signs of pregnancy? Need. To begin with, to confirm that the pregnancy is uterine, and also that the fetal egg was formed precisely in the uterine cavity.

In the normal course of pregnancy, fertilization occurs in the uterine cavity itself. After all, a fertilized egg must reach the site of implantation (through the fallopian tube). If there are any obstacles in the way of the fetal egg (narrowing in the fallopian tube or in the tubal angle of the uterus), and also if the fertilized egg moves for a very long time, or the egg is too large to pass the fallopian tube, then such an egg will not enter the uterine cavity.

In this case, an ectopic or ectopic pregnancy may occur and develop. Remember that an ectopic pregnancy in the earliest period shows the same qualitative reactions as the uterine one. In general, the first signs of pregnancy, discharge for example, are universal for pregnancy in the general case.

A gynecologist can detect only indirect first signs of pregnancy, such as plethora of the external genital organs, discoloration of the mucous membrane of the cervix and vagina. It turns blue (acquires a cyanotic hue). In addition, softening of the isthmus (the place where the body of the uterus and its cervix connects) may be noted.

In general, the body of the uterus may be quite large and soft, and may also appear asymmetrical due to swelling at the site of implantation of the ovum.

The uterine appendages are palpated (felt) by a gynecologist. Sometimes it happens that during a normally developing pregnancy, growths are found in the places where the appendages of the cervix are projected. These changes are usually reversible and the normal structure of the ovary is gradually restored. Such growths may appear as corpus luteum or corpus luteum cysts. However, these formations can also be pathological.

To find out if this is the case, you need to resort to other methods of determining the presence of discharge and other first signs of pregnancy.

Ultrasound of the pelvic organs is the safest method. Depending on which research method is chosen (transvaginal or transabdominal), already three weeks after conception, you can get information about the fact of pregnancy, as well as its localization.
