Recommendations for 12-13 weeks of pregnancy. Development of the circulatory system

The 13th obstetric week of pregnancy is the beginning of the second trimester. The most difficult period is behind us.

What can an expectant mother enjoy this week? What changes occur in the baby's development at 13 weeks?

13 weeks of pregnancy - fetal development, photos, how does the baby develop and feel?

The child's body size has reached 8-10 cm, weight - 20 g. It can be compared to a peach.
The volume of the brain increases, as a result of which its movements become smoother and more orderly.

The head begins to grow more slowly. Limbs lengthen.

What has formed, what is happening, what does the baby look like at the 13th obstetric week?

The sex organs continue to develop this week, but the sex of the baby is still unclear.
In addition, the prostate gland begins to form in boys, and the ovaries in girls.

As a result of the appearance of the sucking reflex, the baby can swallow a small amount of amniotic fluid. In this way, the stomach is prepared for future work.

The pancreas produces insulin, the liver produces bile. The first digestive villi appear in the intestines. The baby produces urine every 40 minutes.

During this period, many pregnant women experience intestinal problems. In this regard, you need to be very careful about your diet.

Changes in a woman’s body at the 13th obstetric week of pregnancy

Chest and abdomen of a woman at 13 weeks of pregnancy

From this week, the expectant mother's belly begins to grow. If it is a multiple pregnancy, it becomes increasingly difficult to hide it.

The breasts are still enlarged in size, although in some women they may shrink slightly due to decreased progesterone.

What can and cannot be done for a woman at 13 weeks of pregnancy?

Physical activity should be moderate. No strenuous sports. The most acceptable option is swimming and yoga for pregnant women.

Walking will also bring maximum benefits. However, walking too long can cause pain in your legs, so their duration should be limited. In order to feel good, a woman simply needs to rest often.

It should be remembered that during pregnancy, concentration decreases. Therefore, you need to drive with extreme caution.

Expectant mothers need to strictly control their diet. Large weight gain during pregnancy is extremely undesirable! In order not to gain extra pounds, you need to reduce your consumption of bakery and confectionery products to a minimum.

Important to know: Pain and cramps in the legs are a sign of calcium and potassium deficiency.

In the second trimester, you should try to eat more protein foods. Protein is needed for the normal functioning of the placenta and the formation of muscle mass in the baby.

13 weeks of pregnancy - how to understand that everything is fine?

The most important sign that everything is fine with the child is stable weight gain. At week 13, the mother should gain from 1 to 2 kg weight.

Test results are also an indicator of the absence of complications. If all indicators are normal, then the expectant mother can be calm.

A sharp decrease in basal temperature is one of the symptoms of a non-developing pregnancy.

Popular questions about pregnancy at 8 weeks - answered by a specialist

13 weeks of pregnancy - obstetric and embryonic periods - how are they different?

• Obstetric term calculated from the beginning of the last menstruation, when pregnancy has not yet occurred. In this way, it is more convenient for doctors to calculate the approximate date of birth.
• Embryonic term– this is the real age of the baby from the moment of fertilization.

Is discharge at 13 weeks of pregnancy normal or a threat of miscarriage?

Due to the increase in fluid volume in the body, vaginal discharge may increase in the second trimester. Normal discharge should be watery and odorless.

White color and thick consistency may indicate thrush. This is not such a rare occurrence among pregnant women. Thrush responds well to treatment, especially in the early stages.

Blood present in the discharge, combined with persistent pain, almost always means a threat of miscarriage.

If at 13 weeks of pregnancy you cannot hear the fetal heartbeat...

It happens that the heartbeat is very difficult to hear.

This happens for several reasons:

• Polyhydramnios or oligohydramnios.
• Placental insufficiency.
• Malformations of the heart.
• Maternal obesity.
• Incorrect placement of the fetus.

If the heartbeat is not heard at all, the reason may be a malfunction of the device's sensor. In other cases, this means the death of the fetus.

If at 13 weeks of pregnancy the lower abdomen feels tight...

Walking in high heels and lifting weights can provoke nagging pain. In this case, the woman needs to take a comfortable position, preferably lying down. After some period of time, the discomfort should go away.

Are you worried about pain or tingling in the ovaries at the 13th obstetric week - reasons?

Rapid enlargement of the uterus causes stretching of the ligaments, which leads to pain in the place where the ovaries are located. Usually such pain appears and disappears suddenly. They pose no threat.

Acute and prolonged pain in combination with elevated body temperature should cause concern.

13th week of pregnancy with IVF - what do doctors do?

At the 13th week of eco-pregnancy, doctors take anthropometric measurements and diagnose cervical pathology using ultrasound.

A blood test is performed to determine the content of pregnancy proteins PAPP-A and the beta subunit of the hCG hormone.

Is it normal if toxicosis suddenly disappears at the 13th week of pregnancy, the nausea stops, I don’t feel pregnant; is there blood?

When a pregnant woman stops vomiting, it may mean that her hormone levels have changed slightly. In this case, there is no cause for alarm.

However, the appearance of blood almost always means problems with bearing a child. To dispel all doubts, a woman needs to see a doctor.

Is it possible to detect a frozen pregnancy at 13 weeks, or does it rarely freeze at this time?

There are certain difficulties in determining a frozen pregnancy.

The first sign that the fetus has stopped developing is the disappearance of toxicosis, which is also natural for this period. For this reason, it is sometimes difficult to recognize a frozen pregnancy in the early stages.

After fetal freezing occurs, other pregnancy symptoms will gradually begin to disappear. A sharp decrease in basal temperature(below 37 degrees) is also one of the signs of frozen pregnancy.

The next symptom that cannot be ignored is blood from vagina.

Miscarriage occurs more often in women who have had a similar experience in the past.

Are ARVI, influenza and other diseases dangerous at 13 weeks of pregnancy?

Many people exaggerate the danger of ARVI during pregnancy. With proper and timely treatment, colds cannot harm the unborn baby.

The most important rule– never self-medicate, as many medications can affect the course of pregnancy.

At week 13, disruptions in fetal development are practically impossible, since all important organs and systems have already formed.

But there is a list of diseases that are considered potentially dangerous during pregnancy:

• Venereal diseases.
• Tuberculosis.
• Measles.
• Rubella.
• Hepatitis.

At 13 weeks of pregnancy, toxicosis disappeared and I feel good

This is a completely expected condition - many women begin to feel better during this period. Just don’t forget to visit your doctor in a timely manner and continue to follow all recommendations.

Many people call this month the golden period. Now a woman can fully experience the pleasure of pregnancy.

This time can be devoted to such pleasant little things as planning a children's room, buying necessary goods for the baby and studying information about childbirth, which will soon be very useful for the mother.

And the emotional stress associated with the fear of losing a child.

Important: at 13 weeks of pregnancy a woman can still have time to pass first– an examination necessary to assess the condition of the fetus and identify its risk of genetic diseases.

What happens to the baby at 13 weeks of pregnancy?

The fruit is still very small: its height is only 7-8 cm, and its weight is 20-25 g. The disproportion of the body parts remains noticeable: the baby’s head is larger than the body, and the arms are longer than the legs. However, from the 13th week, the rate of increase in the baby’s height and weight will accelerate, and he will grow more and not get better. Also, very soon the body proportions will return to normal.

At week 13, the formation of individual facial features of the fetus continues, facial expressions develop (the fetus squints, smacks, and stretches out its lips). A unique pattern appears on the baby’s fingers. The baby's skin is still very thin, but it already has sensitive receptors, and blood vessels are visible through it.

By increasing muscle mass and strengthening the musculoskeletal system The baby manages to learn more and more new movements. He can already somersault, bend, raise his head, swing his arms and legs. Mom doesn’t feel it all yet and won’t feel it for at least a month. By the way, The first fetal movement can be used as a guide when calculating the gestational age. In primiparous women, the baby makes itself known with barely noticeable tremors at approximately 20 weeks of pregnancy, and in multiparous women - at 17-18 weeks.

The development of the child's senses continues. Very soon he will be able to distinguish smells and tastes. The first thing the baby inside the mother will taste is the amniotic fluid, the taste and composition of which largely depend on what the woman eats. This once again confirms the need to eat tasty and healthy food during pregnancy.

At week 13, germ cells are formed in the fetal gonads. The process of formation of the external genitalia is coming to an end. The kidneys begin to function more actively - they secrete urine, which replenishes amniotic fluid reserves.

Mother's well-being at 13 weeks of pregnancy

Disappears completely or noticeably weakens. The woman regains her vigor and desire to put herself in order, to do something around the house or at work. Among the new sensations are swelling and(the appearance of these symptoms is also related to hormones). In addition, it is possible to release colostrum from enlarged mammary glands. In this way, the breast learns to produce milk. Colostrum should not be squeezed out, since stimulation of the nipples can trigger the release of estrogens into the blood, which stimulate uterine contractions.

At the 13th week of pregnancy, the expectant mother may experience(if this has not happened before). You can cope with them by adjusting your diet, drinking regimen and changing some habits. For example, if heartburn is tormented, it is advisable for a pregnant woman not to overeat, not to lie down immediately after eating, and not to abuse spicy and sour foods. With constipation, on the contrary, it is useful to move more. As for the diet, to eliminate problems with bowel movements, you need to drink more, eat lactic acid products, vegetables, fruits, and cereals.

Changes also occur in a woman’s appearance – the waist becomes slightly rounded, and the mammary glands enlarge even more. May appear and hair- this is a sign that there is calcium deficiency. This may also be indicated by emerging dental problems(their increases, development accelerates). If such problems arise, you should definitely contact your dentist, who will select a medicated toothpaste and give recommendations regarding the specifics of oral care during pregnancy.

Possible complications of the 13th week of pregnancy

In general, 13-24 weeks of pregnancy are the safest and most comfortable for both mother and fetus. By 13 weeks The risk of pregnancy loss is significantly reduced. But other problems may appear - lower limbs and(manifests itself as a sharp hardening of the lower abdomen). It is imperative that you report these sensations to your doctor. You may even need special drug treatment.

In addition, quite often in the 13th and subsequent weeks of pregnancy develops thrush –. However, in the first trimester, it is undesirable to treat this disease with antifungal drugs, since the effect of most of them on the fetus is either not well studied or negative. To reduce discomfort, the expectant mother can wash herself with a weak soda solution or plain water with the addition of a few drops of tea tree oil. . The course of thrush is largely influenced by a woman’s diet, especially the abuse of sweets.. In this regard, the expectant mother needs to reduce the amount of sugar in her diet (it is better to give it up altogether for a while), and also consume fresh lactic acid products, best prepared independently from starter cultures. Such yoghurts and kefir will help normalize microflora in the body.

Double test: decryption

In the first trimester (from 10 to 14 weeks), the expectant mother must undergo the first (or double) test. The purpose of this study is to calculate the risk of a fetus having a chromosomal pathology. It is impossible to make an accurate diagnosis (for example,) using this analysis. To diagnose genetic diseases, more serious studies are required, involving the collection of umbilical cord blood or biopsy material from the fetal membranes.

The double test involves determining the concentration in the blood of a pregnant woman of a special plasma protein (associated with pregnancy) and free human chorionic gonadotropin. The release of these substances occurs in all expectant mothers through the membranes of the fetus. In some pathologies (Down syndrome, Edwards syndrome, patent neural tube), the level of determined indicators differs significantly from the norm. However, this can also occur under other conditions (for example, threatened miscarriage, delayed fetal development), as well as when taking medications (in particular gestagens, which are prescribed to many pregnant women who have problems with bearing a fetus).

The numbers obtained during the double test in laboratories are converted into MoM(generally accepted coefficient), which displays how many times this indicator differs from the average (median) for this stage of pregnancy. Normally, MoM should be in the range from 0.5 to 2.0. Ideally, this coefficient should approach 1. Next, the received data is processed by a special program that gives the risk value in numbers, for example 1:250. The lower the number in the denominator, the greater the risk. That is, a risk of 1:100 means that for every 100 pregnancies with the same screening indicators, 1 baby is born with Down syndrome or another genetic pathology. When calculating the risk, the age of the mother and the presence of older children with chromosomal abnormalities must be taken into account.

In addition to the double test, prenatal screening in the first trimester necessarily includes Fetal ultrasound(determination of the thickness of the nuchal space, the presence of a nasal bone and the coccygeal-parietal size). The results of prenatal screening are assessed by a gynecologist. If he discovers that the patient has a high risk of giving birth to a sick baby, he refers her to a geneticist for consultation.

At the turn between the 1st and 2nd trimesters of pregnancy (13th obstetric week or 14th embryonic week), a period begins that expectant mothers call the best time or “golden time.” And there are good reasons for this. Now completely unpleasant signs of toxicosis are becoming much weaker, or even disappearing: nausea, weakness and dizziness, emotional instability.

At the thirteenth week, the expectant mother already feels much better and can fully enjoy her new status and position. Waking up in the morning becomes easy and without annoying nausea and vomiting. The reaction to odors becomes less strong. Blood pressure doesn't increase and you don't feel dizzy.

A pregnant woman begins to feel a surge of strength, an increasingly positive mood, and positive emotions. Sleep and appetite are normalized. The feeling of constant fatigue and drowsiness disappears.

And the best thing now is the opportunity to go shopping for yourself, purchasing maternity clothes for your wardrobe. Narrow and tight clothes and stiletto heels will now have to wait in the closet for quite a long time.

A fascinating activity is already emerging - looking at your slightly rounded tummy in the mirror and imagining what the long-awaited future baby looks like inside.

At this stage, many women notice how their appearance, tormented by toxicosis, gradually turns into simply blooming. The expectant mother, although not yet burdened by a large belly, is already beginning to move differently: more smoothly and carefully. This is a natural reaction of the body - it tries with all its might not to harm the unborn child and protect it from possible injuries.

Fetal development at 13 weeks of gestation

By the end of the 13th obstetric week of pregnancy, the fetus becomes comparable in size to a peach. This is approximately 6.5 - 7.8 cm from the crown to the tailbone, 10-12 cm of total height. The future baby now weighs about 20-30 grams. The head increases in diameter to almost three centimeters.

At this stage, the embryo is already protected by the placenta, which not only protects the fetus, but also produces substances necessary for normal development and growth - estrogen and progesterone.

Now the thickness of the protective cocoon is approximately 16 mm. The placenta allows blood to flow from the mother to the fetus, but acts as a filter to retain all harmful substances that can negatively affect the development of the embryo.

What happens to the baby at the thirteenth week of pregnancy:

• The face is already clearly visible. Ultrasound images can show the features of the unborn baby. True, the eyes are still set quite far apart and are gradually moving closer together. The eyeballs are already covered with eyelids. The head is already slightly raised above the sternum, so the chin, nose and brow ridges are visible. The auricles and earlobes have already been outlined.
• The skin is still very thin; blood vessels can even be seen through it. The baby's skin is now wrinkled. This is because there are no fat cells yet. But on the surface of the skin the embryonic fluff is already visible, which will remain for some time after birth.
• The bone skeleton is actively developing and strengthening. Calcium is deposited, arms and legs become longer, the skull and spine harden. The ribs lag behind, they form and strengthen a little late.
• The brain is developing by leaps and bounds. This progress is noticeable in the behavior of the embryo: the fetus moves and moves more and more. During periods of wakefulness (and they are not very long, because the baby sleeps more and more), the baby reflexively clenches his fists, makes grimaces, wrinkles his nose and pulls his finger into his mouth.
• During this period, baby teeth are formed - there are already about twenty such rudiments.
• The respiratory system has practically formed. The diaphragm makes training movements that will allow the baby to inhale air at the time of birth. Now the mouth is still closed, but it happens that the baby swallows amniotic fluid. Especially when he lacks oxygen.
• Significant changes also occur in the gastrointestinal tract: the pancreas begins to produce insulin. And villi appear in the intestines.

What complications may arise at 13 weeks of pregnancy?

Basically, all possible complications at this time can be caused by insufficient amounts of certain useful substances and microelements in the expectant mother’s body. So, for example, a lack of calcium (and the fetus now actively takes it for the development and strengthening of bones) can negatively affect a pregnant woman - varicose veins are dangerous and not so easy to treat later.

Pay attention to vitamin D - its deficiency may well provoke rickets in a baby.

Changes in a woman’s body at 13 weeks of pregnancy

The hormonal storm has subsided, the restructuring of the female body to carry a pregnancy is almost complete. All that remains is to wait and prepare for an important event - the birth of a child. At this stage, all the organs of the unborn baby are already formed. The embryo grows and develops, and the bond between mother and fetus becomes stronger.

The entry into the female body of substances that suppress the immune system (to avoid fetal rejection) is stopped. The embryo is already firmly established in the uterus, it is surrounded by a protective membrane - the placenta. The uterus itself grows along with the baby, so the tummy is steadily increasing and the figure is rounded.

A hormone such as somatotropin helps improve the appearance of a pregnant woman. This substance seems to highlight facial features and give the expectant mother an attractive appearance.

At the thirteenth week of pregnancy, the breasts increase in size, and in some cases very significantly. The mammary glands are preparing for feeding. The nipples remain very sensitive. The areola around them becomes large and darkens.

It is worth saying that at this time the body is almost ready for pregnancy. The main task now is to provide the fetus with everything it needs for its normal development. This is why blood volume increases significantly. After all, it is through the blood that the fetus receives beneficial substances from the mother. Also. The rate of metabolism in the body of the expectant mother also increases.

Tests and medical examinations

Usually, by this time, a diligent pregnant woman has already registered for pregnancy at the antenatal clinic. After all, after the 12th week, a woman already loses the right to receive a lump sum pregnancy benefit.

By the 13th week, the pregnant woman has already passed the entire necessary set of tests, and now all that remains is to come for examinations as prescribed by the gynecologist. At this time, you can also make visits to doctors of other specialties (ENT, dentist, therapist, endocrinologist, ophthalmologist, etc.). This is especially important if you have any chronic diseases. Doctor’s supervision is a kind of safety net against all unwanted complications.

At 13 weeks, the doctor will measure the pregnant woman’s weight and abdominal circumference. Controlling your weight gain is important. After all, the current good appetite can lead to unwanted fullness and even obesity.

Blood pressure may jump. A slight fluctuation in the indicators is not dangerous. But sharp jumps in blood pressure are a reason to seek advice from a specialist.

At this time, the doctor may prescribe additional examinations. Such, for example, as a double biochemical test to determine PAPP, ultrasound or a blood test for b-hCG. These studies will show how high the risk of any genetic or chromosomal abnormalities or diseases is.

Sometimes a biopsy (sampling of chorionic villi tissue) or amniocentosis (puncture of the amniotic sac with sampling of amniotic fluid) is prescribed. However, it is worth remembering that these tests carry certain risks, because there is direct intervention in the uterus. Therefore, such studies are prescribed only strictly according to medical indications and only with the written consent of the woman. The results (which, however, take quite a long time to determine) will reveal the presence of many serious pathologies (Down syndrome, for example). But early diagnosis will allow you to correct the development of the fetus and reduce the risk of even greater complications.

A test for the level of hCG in the blood may also be prescribed. But it should be remembered that now the number of units is gradually declining. The norm at this time is 20900-291000 mIU/ml. a decrease in hCG leads to a reduction in the unpleasant sensations of toxicosis in pregnant women.

Ultrasound at 13 weeks of pregnancy

An ultrasound scan at the 13th obstetric week of pregnancy is prescribed upon registration at the antenatal clinic. During this period, the ultrasound specialist will check whether the placenta is positioned correctly, listen to the heart rate of the embryo, and check whether the motor activity of the fetus is high enough.

Now an ultrasound examination is used to determine the collar zone. After all, this is an important indicator for identifying genetic abnormalities.

To diagnose isthmic-cervical insufficiency, the condition of the uterine pharynx is examined.

Now the whole life of a pregnant woman is focused only on how to carry and give birth to a child without complications. The expectant mother is both physically and mentally preparing for the fact that now she will do everything only for the benefit and normal development of the fetus. After all, every mother wants her baby to be born healthy and strong.

As already mentioned, the formation of all fetal organs has already occurred. Now the main thing is to provide the embryo with all the substances necessary for growth and development. Therefore, special attention is paid to proper and nutritious nutrition.

Take the time to sit down and create a diet for yourself in accordance with the recommendations of doctors and nutritionists.

Pay attention to vaginal discharge. They should normally be transparent or slightly whitish, perhaps a little more abundant than before. But the appearance of an unpleasant odor, curdling, itching, discoloration, inclusions of blood - this is a reason for an immediate visit to the doctor.

Prohibitions and contraindications during pregnancy

All bad habits remain prohibited as before. And although the placenta now protects the fetus, it will not be able to filter out all harmful and toxic substances entering the blood. Therefore, definitely no alcohol, cigarettes, drugs, toxic paints, aggressive household detergents and cleaners, or ionizing radiation exposure.

Of course, no one conducted experiments on pregnant women that could show in what doses alcohol would not harm the unborn child. However, observations of children born to mothers who abused cigarettes and alcohol show a rather depressing picture. Agree, it’s simply scary when a newly born baby is already experiencing “withdrawal” from a lack of ethanol or nicotine in the blood.

So, what is prohibited for a expectant mother in the thirteenth week of pregnancy:

• Bad habits (alcohol, smoking, drugs)
• Uncontrolled use of medications and self-medication in the event of any disease. The same, by the way, applies to folk remedies - herbs and tinctures
• Harmful working conditions
• Physical fatigue
• Stress
• “Wrong” foods in large quantities: fatty, salty, fast food, etc. Don't overeat on sweets, which will cause unnecessary wrinkles on your sides and stomach.

Sex at 13 weeks pregnant

The ban applies only to cases where there is a risk of miscarriage or placenta previa is observed.

If everything is normal, toxicosis has gone away, then why not enjoy the pleasant sensations of sex. Moreover, many pregnant women say that sexual relations now seem to take on new colors and emotions and become more intense.

Sports and physical education

We continue to engage in moderate physical activity. We do yoga or gymnastics for pregnant women, swim in the pool.

The main thing is that there should be no overwork and overload. Therefore, stop extreme sports and professional sports.

Vitamins and medications at 13 weeks of pregnancy

As mentioned above, taking medications is not recommended now. Or only for strict medical reasons and after consultation with a doctor. Medicines can cause enormous harm if taken uncontrolled.

As for folic acid, the 13th week is the last week when it should be taken. Vitamin complexes or iodine-containing preparations are not prohibited. You just have to make sure that there is no excess of substances - hypervitaminosis.

From conception. If we consider ordinary months, then you are now in the third month, or the beginning of the fourth lunar month. Also this week marks the boundary between the first and second trimesters. Since there are no strict divisions, some gynecologists consider the 13th week to be the second trimester, while others do not.

This is the calmest period in the life of the expectant mother and her baby.

Feelings in a woman at 13 weeks of pregnancy

Like the previous ones, the thirteenth week brings mixed feelings to a woman. On the one hand, the sensations are pleasing and filled with incredible anticipation, but on the other hand, you begin to understand that your carefree life has passed, and now you are constantly responsible for your baby, which makes it a little difficult to feel completely free.

The path to motherhood is filled with challenges and excitement. It is especially difficult for women who are expecting their first child. Thoughts are constantly spinning in my head: will I have enough strength and health to bear and give birth to a healthy child?

And then, as luck would have it, all my friends begin to talk about various complications that can arise during pregnancy and childbirth. These stories cannot leave even a mentally balanced person indifferent, and they often bring expectant mothers to tears and nervous breakdowns.

But still the emotional state of the pregnant woman on this line becomes more stable and positive. This is due to the fact that toxicosis of the first half bothers her less and less. Manifestations of autonomic dysfunction, which affected mood stability in the first three months, gradually disappear. The woman feels more comfortable and has an incredible surge of strength.

Quite often women at this stage are concerned about:

• Constipation, the cause of which is a violation of intestinal peristaltic function, which occurs against the background of hormonal changes. A uterus that is constantly growing and leaves less and less space for the intestines, which also causes constipation;
• Convulsions in the calf muscles, which most often appear at night. The cause of this condition is a lack of calcium in the woman’s body.
• Hypotension(decrease in blood pressure), which can occur after the formation of the placental-uterine circulation. Most often, a woman suffers this disease without obvious discomfort. But if the pressure drops significantly, then it is better to resort to drug treatment. With very low pressure, peripheral blood vessels contract, including those in the uterus, which can cause insufficient blood supply to the fetus.
• If on this line blood pressure rises, then most likely this is due to kidney disease, and not a predisposition to hypertension.

Forums: What do women write about their well-being?

Anna:

Hooray! The second trimester has already begun. I feel great, in a week I’ll go for an ultrasound, I’ll finally see my baby.

Natasha:

The tummy has grown a little. The clothes no longer match. Need to go shopping.

Inna:

My toxicosis will not go away.

Olga:

I feel great, just a little irritable, and I start crying for any reason. But I think this will pass soon.

Masha:

I feel great. There was and is no toxicosis. If I hadn’t seen my baby on an ultrasound, I wouldn’t have believed that I was pregnant.

Marina:

The tummy has become slightly rounded. Toxicosis is no longer a concern. I'm expecting a miracle.

What happens in a woman's body?

• Your body has already produced enough hormones that are responsible for maintaining the child. Therefore, soon you will no longer be bothered by morning sickness. You will no longer worry about a possible miscarriage, and you will become less irritable;
• The uterus is increasing in size and now it is about 3 cm high and 10 cm wide. Gradually it begins to rise into the abdominal cavity from the pelvic floor. There it will be located behind the anterior abdominal wall. Therefore, your relatives and friends may notice a slightly rounded tummy;
• The uterus becomes more elastic and soft every day. Sometimes a woman notices minor vaginal discharge that is not cause for concern. But if they have an unpleasant odor and a yellowish color, be sure to consult a doctor;
• You've probably already noticed that your breasts began to increase in size, this happens because milk ducts develop inside it. In the second trimester, with a light massage, a yellowish liquid may appear from the nipples - colostrum.

Fetal development in the 13th week

For your unborn baby, the thirteenth week is very important. This is a key moment in the formation of the relationship between mother and fetus.

The placenta completes its development, which is now fully responsible for the development of the fetus, producing the required amount of progesterone and estrogen. Now its thickness is about 16 mm. It passes through itself all the microelements necessary for the child (fats, carbohydrates, proteins) and is an insurmountable barrier to many toxic substances.

Therefore, it is possible to treat the mother’s disease, for which it is necessary to use medications (antibiotics). The placenta also protects the fetus from influences from the mother’s immune system, preventing the occurrence of Rh conflict.

Your baby continues to form and develop all the systems necessary to support life:

• Begins to develop rapidly brain. The baby begins to develop reflexes: his hands clench into fists, his lips curl, his fingers reach into his mouth, he grimaces, he shudders. Your baby spends some time actively, but still sleeps more. Fetal movements can only be detected using instruments;
• Continues to be actively formed fetal skeletal system. The thyroid gland has already developed sufficiently and now calcium is deposited in the bones. The bones of the limbs lengthen, the first ribs form, and the bones of the spine and skull begin to ossify. The baby's head is no longer pressed to the chest and the chin, brow ridges and bridge of the nose can be clearly identified. The ears are in their normal position. And the eyes begin to come closer together, but they are still closed with tightly fused eyelids;
• Develops very tender and thin skin covering, there is practically no subcutaneous fatty tissue, so the skin is very red and wrinkled, and small blood vessels appear on its surface;
• Respiratory system The baby is already quite well formed. The fetus is breathing, but the glottis is still tightly closed. His breathing movements train the muscles of the diaphragm and chest more. If the baby suffers from a lack of oxygen, a small amount of amniotic fluid may enter the lungs. Therefore, if a pregnant woman is sick and there are pathogenic bacteria in the amniotic fluid, this can cause an intrauterine infection;

At the end of the 13th week your baby's length will be about 10-12 cm, and the head has a diameter of approximately 2.97 cm. His weight is now about 20-30 g.

At this stage, the threat of miscarriage is significantly reduced, but there are still cases of spontaneous abortion. Therefore, the expectant mother should monitor her health, since the flu and even a common cold can harm your baby.

• Avoid heavy physical activity;
• Do not self-medicate;
• In the autumn-winter period, use natural methods to prevent colds and flu: hardening, wash your hands after going outside, do not visit crowded places;
• Don't forget about proper nutrition: eat more dairy products, fresh vegetables and fruits. To avoid constipation, eat foods that have a laxative effect: prunes, beets, plums and bran. Don’t get carried away with rice, pears and poppy seeds, they strengthen;
• Spend more time outdoors, walk, communicate with people you like;
• Do not use industrial cosmetics, use natural ones instead.
