Height – 26-27 cm, weight – 400 g.
From 20 to 24 weeks, the development of all the basic life support systems for the child continues. The cardiovascular system begins to produce white blood cells. They are responsible for immunity and protection against infections.
The red blood cells in the blood are already high enough. The rumor develops – auditory courses have already formed, which through sensitive nerves have established complex connections with the brain.
The genitourinary system is active. The urine of the child is regularly released into the amniotic fluid and processed there. The volume of amniotic fluid this week is about 500 ml. If the kidneys work poorly, then the amniotic fluid is formed too little, in rare cases, it does not form at all.
Otherwise – with an extremely large amount of amniotic fluid – a ruptured bladder rupture and, as a result, premature birth may occur. Therefore, pay attention to the indicator of the state of amniotic fluid when you do ultrasound.
The digestive system divides the amniotic fluid that the child swallows actively, separates sugar and water from it, and lets the fibrous contents pass to the rectum.
In the intestine is formed meconium – the original feces. This substance consists of the remains of an amniotic fluid that the baby has not learned. Typically, meconium is secreted from the intestine only a few days before and after delivery. Thus, during the rest of the time, the amniotic fluid should be clear and free of meconium traces.
If the meconium gets into the amniotic fluid, the baby can swallow it and, if it gets into the lungs, pneumonia can be caused. The allocation of meconium can be caused by contraction of the intestine because of the discomfort experienced.
If the analyzes show traces of meconium in the waters, you should definitely pay attention to it. Meconium in the waters – an indicator that something is not in the ideal order, but the baby suffers.
The Kid is still not grown enough to occupy the entire space of the uterus. Therefore, he moves in his pleasure, turns over several times a day. This is the period of the most active behavior of the baby. Then he will grow even more and will not be able to behave as unconstrained as now.
Sometimes mothers experience even unpleasant sensations, especially when their offspring begins to beat legs in the liver, kidney and stomach, or rest against the diaphragm so that it is difficult to breathe. But no matter how grumbling moms, if the baby quiet down for an unusually long time, any of them will be tormented by anxiety, whether something happened.
Actually, a kid can just fall asleep deeply – after all, he needs rest. Therefore, panic costs 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 accumulated rapidly, it is possible that you significantly exceed the average. Now, not only do you become fuller, but the child begins to postpone fat, which will serve him as an excellent thermoregulator after childbirth.
It also happens that the weight is added very unevenly. Some women can suddenly suddenly add 2-3 kilograms in a few days, and then the weight stabilizes and does not grow for a week or two. Many have “kickbacks”: an increase – weight loss – an increase – weight loss. It turns out that they are full of some jumps.
Your uterus rises above the navel by 1 – 1.2 cm. It presses against your navel and it starts to stick ridiculously ridiculously, instead of being as usual a hollow. By the end of pregnancy, your navel will resemble a button-button.
The height of the bottom of the uterus is on average 21 cm (plus or minus 2 cm). Now it is more and more like the shape of an egg. The walls of the uterus become thinner and stretch, but the bottom 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 will be better if you get them with useful products, and not with hamburgers or snickers. But it also happens that pregnant women need a certain product, they want it to tremble in their hands and knees.
This product can be anything. Even the same hamburger. Sometimes tastes become completely strange, then women can eat land, leaves, almost raw steaks, etc. This is called “perverted appetite”. Do not be afraid, it’s okay, it’ll all go away soon.
Do not forget that you must walk. If you work, then try to change your pose more often. You can not just sit or just stand, alternate the position of the body, stretch your legs – so it will be easier for your child.
If you are sitting, try not to put your foot on your leg, this leads to the fact that they, at least, become numb, and as a maximum you can earn complications on the veins.
Sometimes after the 20th week of pregnancy, women are worried about swelling. This is one of the signs of gestosis (a disorder of the vascular system and blood flow in pregnant women), so you should take them seriously.
What are the signs of swelling:
– on your fingers do not fit the rings that you used to wear;
– feet and fingers swelled;
– tap with your finger somewhere in the ankles or wrists area. If the skin is smoothed out immediately – everything is fine, if the pits are left for a while – this is an edema;
– abnormal weight gain.
Plus to this, all complaints of fatigue and dizziness (down to the “flies in the eyes”). If there is also protein in the urine and increased blood pressure, then you can have nephropathy (kidney damage), then the treatment is performed in the hospital.
The launched situation can flow into the stage of placenta aging and fetal hypoxia. We recommend that you regularly check your body for puffiness. If the edema is only on the legs – this is normal, you should not worry.
Just the body now does not have enough fluid – everything goes to increase the blood volume of the baby. That’s why Mom wants to drink more. You should start worrying if you find swelling on the thighs, knees, abdomen.
The treatment methods are as follows:
– do not reduce water intake, it should be consumed 1.5 liters per day (fruit, soups, etc. does not count);
– raise your legs more often, it will be even better if you hold them for 20 minutes in a basin with cool water;
– do not abuse salt, sweets and fizzy drinks (this delays the withdrawal of fluid from the body);
You can apply special gels from swelling;
– massage the feet with special washcloths;
– drink cowberry compote, tea with lemon without sugar, water with lemon, a glass of hot milk for the night;
– You can do one fasting day a week (apples and juice).
It is absolutely forbidden to use diuretics and kidney teas. Any drug intervention, including from the field of phytotherapy, should be carried out only after consulting a doctor.
