21 weeks of pregnancy. Half way behind

There comes 21 weeks of pregnancy, which means that half the way is already passed. This can be called a kind of a frontier. Many unrest left behind. Mom has already become accustomed to her special situation, both physically and psychologically. The second half is calmer, many by this time completely disappear all manifestations of toxicosis, calmly and in terms of threat of termination of pregnancy, the main fears are left behind.

And how does the fetus feel at 21 weeks of pregnancy? Its weight is about 350 grams, and the length is about 28 centimeters. The skin still has a reddish tinge, but it is no longer so transparent. Color and transparency change due to the beginning of deposition of subcutaneous fat. Every day the fat becomes more and more and the baby gradually loses its former wrinkles. The skin is covered with a light lanugo fluff, in some places a damp grease appears. On the face are formed crotch and cilia. Internal organs become more and more perfect, muscles are gradually built up.

The baby begins to swallow the amniotic fluid, which is already digested by a fully functioning intestine. From the undeveloped remainder in the intestine is formed meconium, or, in another way, the original feces. It includes the baby's hair, epidermis scales, the secretion of the sebaceous glands and has a greenish, almost black hue.

At this time the fetus begins to perceive various sounds, they reach it in the form of vibrations and vibrations. Mummy can notice that if suddenly there will be a sharp and loud sound, the kid will be frightened and will start to stir actively.

Usually, at this time, the doctor appoints an ultrasound procedure. 21 weeks of pregnancy is quite interesting, the mother can see how the baby swallows the amniotic fluid, actively stirs the arms and legs. In this period, without any special problems, you can discern the sex of the baby, if, of course, he wants it and does not hide an interesting place behind the crossed legs.

Since 21 weeks of pregnancy is abroad, you can sum up the restructuring of the woman's body.

The load on the cardiovascular system is quite high due to the appearance in the body of an additional circle of blood circulation. The total volume of blood increased by 500 milliliters, the pulse becomes more frequent, about 90 beats per minute. The pressure is higher than the previous level by about 10 millimeters of mercury.

If you compare the indications in the blood tests at the beginning of pregnancy and now, when it's already 21 weeks of pregnancy, they will be significantly different. Leukocytes in the blood become larger, accelerated ESR, and the volume of plasma increases. During this period, anemia of pregnant women is quite common, therefore the doctor regularly appoints a blood test for biochemistry. A reduced amount of iron is dangerous, with its deficiency, women are prescribed iron-containing preparations and a special diet that includes liver, tomato juice, apples, buckwheat.

Do not miss and surrender urine tests. The growing uterus compresses the mouth of the ureters and the bladder, preventing a normal outflow of urine. This can lead to a fairly common pyelonephritis of pregnant women. This is due to stagnation of urine and development of infections against this background. At the same time, painful urination, back pain, general weakness can hide. The main thing is to warn the development of the disease in time, the disturbance of the excretory function also harms the baby. The intake of nutrients deteriorates, moreover, unfortunate slags from the blood damage. If there is a predisposition to pyelonephritis, then it is recommended to periodically get on all fours for prevention, thereby provoking the best outflow of urine.

If there is 21 weeks of pregnancy and above, it is simply unacceptable to skip the delivery of tests.
