Twentieth week of pregnancy

Future child.

Height – 24-25 cm, weight – 300-350 gr.

Finally! Behind half of pregnancy. The kid has become the size of a large banana. Mothers who give birth for the first time can feel the movements of their child, if they have not felt them before. Those who give birth not the first time, usually feel “shchevelyushki” 2-3 weeks earlier.

If the pope puts his ear to the belly of his mother, he will be able to disassemble the heartbeat of the baby. And in any case, the heartbeat is well audible through the stethoscope.

Watching the jerks and kicks, the mother can accurately determine when the baby is sleeping, and when playing. She can even play with him herself, if she touches her abdomen in different places. After a while, the kid understands the game and responds with a jolt to the area where the mother’s hand is located.

You can talk with your child, this is especially helpful if he is too restless himself. From the sound of my mother’s voice and her stroking, the baby usually calms down pretty quickly.

If you feel small, rhythmically repetitive jerks, it is most likely a hiccup. After all, the baby swallows daily up to 14 ml of amniotic fluid, from which it receives additional nutrients and hormones. How can I do without a little not to look!

Kidneys and intestines work hard. On the day of the baby 7-14 ml of urine is formed, and in the intestines of meconium (original feces). Meconium, you can see for yourself: in the first day or two after birth, your baby will defecate to them until he is replaced by ordinary children’s feces.

The skin of the baby consists of two layers already: the epidermis and the dermis. On his head and body appears the so-called original grease. This is a special substance of white-cream color, protecting the baby’s skin from damage and germs.

The substance is formed from the secretions of the sebaceous glands and the remnants of skin cells. Basically, it accumulates in the groin, on the folds of the arms and legs, on the head. Often lubrication is preserved until delivery and it will be wiped by the midwife, after the baby is born.

The baby’s body begins to gain muscle and fat. It grows fuller and rounds. Usually from this week, doctors are watching to ensure that mom does not overeat buns and cakes, otherwise the baby can grow to 4-5 kg, and giving birth to such a hero is much more difficult than a child of “elegant” sizes (3-4 kg). On his face there are distinct cilia and eyebrows.

US examination already easily determines the sex of the child, as well as the actual gestation period, the approximate date of delivery. The ultrasound will also show fetal anomalies, if any.

Future Mom.

If you work, there are only 10 weeks left until maternity leave. It’s time to finish all your current affairs and prepare for the most important – the birth of the baby and his first year of life.

This period is a real flowering of pregnancy. A woman’s breathing comes from somewhere. She is cheerful and full of strength, often builds and, more strangely, realizes the most fantastic plans. Her skin, her hair, her eyes shine with a special light, full of brilliance and beauty.

This week, the sensations of fetal movement should be quite distinct. If you still do not feel them, then you should take a closer look. Maybe you are taking a stir for something else?

The gain in weight begins to be rapid and is now 4.5 – 5 kg. Prepare for the fact that you can continue to grow 0.5 kg per week! It is easy to estimate that you have ahead of 10 additional kilograms. Try not to exceed this figure. If you are already full of excess, we recommend that you take a closer look at what you eat or consult with doctors.

So, your tummy is no longer impossible to notice and you are finally beginning to give way to transport! The bottom of the uterus reached the navel. She grew up and presses on the kidneys, stomach and even lungs.During the following weeks, you will increasingly run to the toilet (pressure on the bladder), it may begin dyspnea (pressure on the diaphragm, will pass 4-6 weeks before delivery after the stomach falls).

The height of the bottom of the uterus (as doctors call it the length) at 20 week is 18-24 cm (usually exactly 20). You have already noticed that every time you visit a doctor, he always measures your stomach with a centimeter. He checks the correspondence of the size of the uterus to the periods of pregnancy.

If you wish, you can do this simple procedure yourself. As a starting point, a place is taken over the urethra where pubic bones are found. Feel it in your lower abdomen, just below the hairline. Sensations can even be a little painful. The bottom of the uterus at 20 week is at the level of the navel. Measure the distance between the top and bottom point. Check the values ​​that you got.

Pregnancy (week) – Height of the uterus (see)
8-9 weeks – 8-9 cm
10-13 weeks – 10-11 cm
14-15 weeks – 12-13 cm
16 -17 week – 14-19 cm.
18-19 week – 16-21 cm.
20-21 week – 18-24 cm.
22-23 week – 22-23 cm.
24-25 week – 24- 25 cm.
26-27 week – 26-27 cm.
28-29 week – 28-29 cm.
30-31 week – 30-31 cm.
32-33 week – 32-33 cm.
34- 35 weeks – 34-35 cm.
36-37 week – 36-37 cm.
38-39 week – 38-39 cm.
40-41 week – 40-41 cm.

From 20 weeks there is an increase in the height of the bottom the uterus is approximately 1 cm per week. Therefore, when measuring, you should get a result equal to your pregnancy period (plus or minus 2 cm). Lagging by 3 cm is considered pathological.

If the height of the uterine fundus is less than the gestational age, then it is possible:
– an error in the established term of pregnancy;
– water scarcity;
– retardation of fetal development;
– fetal development anomaly.

If, on the contrary, the height of the uterine fundus exceeds the gestational age, then we can assume:
– an error in the timing;
– polyhydramnios;
– multiple pregnancies;
– the child is one, but large.

If the height of the uterine fundus does not significantly correspond to the gestational age, additional tests (ultrasound, cardiotocography, Doppler) are prescribed. By the way, about the research. You should visit your doctor, take a general blood test, analyze urine and, possibly, a hemostasiogram with D-Dimer.

The hemostasiogram evaluates your blood for how it clots or vice versa, resists clotting. It is very important to know in order for your birth to proceed normally. If the blood coagulation system is too high, thromboses can occur in the mother and, most importantly, in the blood vessels of the placenta. A particularly bright marker for thrombosis is D-Dimer.

If, on the contrary, the blood coagulates badly, then bleeding, placental abruption and other troubles are possible. To give the analysis it is necessary on an empty stomach. If you are already drinking any drugs that affect blood clotting, this is noted on the analysis sheet. Quite often, the doctor even recommends that you stop taking these medicines several days before the analysis in order to get more accurate data.

Also at the time of 20 weeks (at an interval of 18-22 weeks), ultrasound is performed. Ultrasound shows the main parameters of the development of the baby:

1) Length of the femur and tibia.
18 week – 28 mm thigh, 23 mm tibia;
19 weeks – 31 mm thigh, 26 mm thigh bone;
Week 20 – 34 mm thigh, 29 mm thigh bone;
21 weeks – 37 mm hip, 32 mm tibia;
22 weeks – 40 mm thigh, 34 mm tibia;

2) The transverse size of the abdomen.
Week 18 – 44 mm;
Week 19 – 50 mm;
Week 20 – 52 mm;
21 weeks – 55 mm;
Week 22 – 59 mm.

3) The biparental dimension of the head. This makes it possible to see if the baby has such developmental defects as hydrocephalus, anencephaly, cystic formations.
Week 18 – 42-43 mm;
Week 19 – 44-46 mm;
Week 20 – 47-50 mm;
21 weeks – 51-53 mm;
22 week – 54-56 mm.;

4) The thickness of the occipital bone can finally cast aside suspicions of Down’s syndrome (if its thickness is not more than 5 mm).

During this ultrasound, the sex of the child is very clearly established, both on its genitals and on the basis of body size (in boys and girls, the proportions are slightly different). The doctor must carefully consider the internal organs of the baby and its limbs, as they are located, shaped and act.

During ultrasound, dopplerography is also performed (popularly called doppler). This study of blood flow in the vessels of the uterus, umbilical cord, placenta and baby. Normal Doppler indices are a sign that the development of the child is currently proceeding well, although some complications are possible in the future.

Therefore, Doppler is usually performed on each ultrasound, especially after 30 weeks. And if there are any doubts in the development of the placenta, the amount of amniotic fluid, the timing of pregnancy, the size of the baby, or the mother’s history of diabetes, kidney disease or anemia, then Doppler is mandatory.

19 weeks – 20 weeks – 21 weeks
