How big is the fetus at 21 weeks of pregnancy and how big is the fetus at 20 weeks of pregnancy

The healthy development of the fetus after pregnancy is a concern for every family, so it is necessary to go to the hospital regularly for check-ups after pregnancy to keep abreast of the development status of the fetus. The fetus grows as the months increase. So, how big is a fetus at 21 weeks pregnant?

Twenty-one weeks of pregnancy belongs to the second trimester, and the fetus is basically stable during this time period, and the fetus is generally about 21 weeks old, with a double parietal diameter of about and a femur growing of about one. Generally, due to the inaccurate menstrual cycle, there may be some deviations, and you can go for a follow-up examination after a week. If the development is still uncoordinated and the development is stunted, the fetus may be malformed, and labor needs to be induced.

The fetus has already had movements in the second trimester, but there is no regularity, only slight movements. At this time, the pregnant woman's belly has also risen slightly, the baby's eyebrows and eyelids have begun to grow, and the hands and feet have also begun to grow nails. At this time, the fetus already has hearing and can hear the outside world, so you can start prenatal education and communicate more with the fetus.

Women will have pregnancy reactions in the first trimester, with symptoms such as dizziness, vomiting, and mental disorders, which are difficult to bear, but by the time they reach 21 weeks, these reactions have basically disappeared. In the third trimester, because the fetus has basically developed perfectly, the pregnant woman's belly has become very large, and the pregnant woman's actions are very unchanged, and the fetus is too large, which may squeeze the stomach. Relatively speaking, twenty-one years is a relatively comfortable stage.

How big is a 20-week baby? The changes in the mother's belly are also visible, and it is great to do prenatal education at this time. As the belly slowly grows bigger day by day like a balloon, the mother's curiosity about the baby's growth and development grows more and more.

When the fetus is 20 weeks old, some mothers have already made an appointment to do three-dimensional or four-dimensional color ultrasound, and when we get the baby's B-ultrasound single, we have already seen the first photo of the baby's life.

3. And because of the enlargement of the uterus, the surrounding organs are squeezed aside.

The obvious feeling is that the bladder is squeezed and the urine becomes more, and the amount may not be more, but the number of urine is increased.

Some mothers feel that their stomach is easily bloated, and their stomach is hungry but their stomach is distended is the feeling of mothers during this period. And constipation has also begun to bother many mothers.

In addition, pregnant women should not smoke, drink alcohol or use drugs during the pregnancy branch clearance, as these bad behaviors can have a great impact on the fetus and can even lead to serious consequences.
