Height - 26-27 cm, weight - 400 g.
From 20 to 24 weeks, the development of all basic life support systems of the child continues. They are responsible for immunity and protection against infections.
The content of red blood cells in the blood is already quite high. Hearing is developing - the auditory canals have already formed, which, through the sensory nerves, have established complex connections with the brain.
The genitourinary system is actively working. The baby's urine is regularly secreted into the amniotic fluid and recycled there. The volume of amniotic fluid this week is about 500 ml. If the kidneys do not work well, then too little amniotic fluid is formed, in rare cases it is not formed at all.
Otherwise, with an extremely large amount of amniotic fluid, rupture of the fetal bladder and, as a result, premature birth may occur. Therefore, pay attention to the indicator of the state of amniotic fluid when you do an ultrasound.
The digestive system separates the amnitic fluid, which the child actively swallows, separates sugar and water from it, and passes its fibrous contents to the rectum.
In the intestine, meconium is formed - the original feces. This substance consists of the remains of amniotic fluid, which the baby has not absorbed. Usually, meconium is excreted from the intestines only a few days before and after childbirth. Thus, the rest of the time, the amniotic fluid should be transparent and without traces of meconium.
If meconium gets into the amniotic fluid, the baby can swallow it and, if it gets into the lungs, pneumonia can be caused. The release of meconium can be caused by contraction of the intestines due to the discomfort experienced.
If analyzes reveal traces of meconium in the waters, be sure to pay attention to this. Meconium in the waters is an indicator that something is not in perfect order, and the baby is suffering.
The baby is still not big enough to take up the entire space of the uterus. Therefore, he moves for pleasure, turns over several times a day. This is the period of the most active behavior of the baby. Then he will grow up even more and will not be able to behave as at ease as now.
Sometimes mothers even experience unpleasant sensations, especially when their offspring begins to kick in the area of the liver, kidneys and abdomen, or rest against the diaphragm so that you can hardly breathe. But no matter how the mothers grumble, if the baby calms down for an unusually long time, any of them will suffer from anxiety, if something has happened.
In fact, the baby can just fall asleep deeply - after all, he needs rest. Therefore, it is worth panicking only if the child does not move for more than 1.5 days, and at the same time you develop a problem pregnancy or have physical injuries.
The average weight gain this week is about 5.5 kg. Weight will be gaining rapidly, it is possible that you will significantly surpass the average. Now not only you yourself are getting fat, but the baby also begins to store fat, which will serve as an excellent thermoregulator for him after childbirth.
It also happens that the weight is added very unevenly. Some women can suddenly add 2-3 kilograms suddenly in a matter of days, and then the weight stabilizes and does not grow for a week or two. Many people also have "kickbacks": gain - weight loss - gain - weight loss. It turns out that they get fat in some jumps.
Your uterus rises above the level of the navel by 1 - 1.2 cm. It presses on your navel and it begins to bulge ridiculously, instead of being as usual a depression. By the end of your pregnancy, your belly button will look like a button.
The average height of the uterine fundus is 21 cm (plus or minus 2 cm). Now it looks more and more like an egg. The walls of the uterus become thinner and stretched, but the fundus of the uterus is slightly denser than the rest of the body.
Many women at this time feel a brutal appetite. Still would! The metabolism is so intense that you need an additional 500 calories per day. Of course, it's best if you get them with wholesome foods rather than hamburgers or sneakers. But it also happens that pregnant women need a certain product, they want it to tremble in their hands and knees.
Anything can be this product. Even the same hamburger. Sometimes the tastes get very strange, then women can eat soil, leaves, almost raw steaks, etc. This is called "perverse appetite". Don't be afraid, it's okay, everything will pass soon.
Do not forget that you definitely need to walk. If you are working, then try to change your posture often. You can't just sit or just stand, alternate body positions, stretch your legs - this will make it easier for your child.
If you are sitting, try not to cross your legs, this leads to the fact that they, at least, become numb, and as a maximum you can earn complications on the veins.
Sometimes, after 20 weeks of pregnancy, women are worried about edema. This is one of the signs of gestosis (disorders of the vascular system and blood flow in pregnant women), so they must be taken seriously.
What are the signs of edema:
- rings that you wore before do not fit on your fingers;
- feet and fingers are swollen;
- Press with your finger anywhere in the ankle or wrist area. If the skin is smoothed out immediately, everything is fine, if a fossa remains for a while, this is swelling;
- pathological weight gain.
Plus to all this complaints of fatigue and dizziness (up to "flies in the eyes"). If there is also protein in the urine and high blood pressure, then you may have nephropathy (kidney damage), then the treatment is carried out in a hospital.
A neglected situation can flow into the stage of aging of the placenta and fetal hypoxia. We advise you to regularly check your body for swelling. If there is swelling only on the legs, this is normal, you should not worry.
It's just that the body now lacks fluid - everything goes to increase the baby's blood volume. Therefore, mommy wants to drink more. You should start worrying if you find swelling in the hips, knees, abdomen.
The treatment methods are as follows:
- do not reduce water consumption, you should drink it 1.5 liters a day (fruits, soups, etc. do not count);
- raise your legs up more often, it will be even better if you pre-hold them in a basin of cool water for 20 minutes;
- do not abuse salt, sweets and carbonated drinks (this delays the removal of fluid from the body);
- you can use special gels for edema;
- massage your feet with special washcloths;
- drink lingonberry compote, tea with lemon without sugar, water with lemon, a glass of hot milk at night;
- you can do one fasting day a week (apples and juice).
It is strictly forbidden to use diuretics and renal teas. Any medical intervention, including from the field of herbal medicine, should be carried out only after consulting a doctor.
