Seventh week pregnancy symptoms

The seventh week of pregnancy is a period of fetal development and growth is relatively fast. Changes in the fetus can be clearly observed. At this time, the fetus is about one centimeter long and weighs about four grams. It has already taken human shape and physical examination shows that it is fully differentiated. The shapes of the head, body, hands and feet can be clearly seen. In addition to these manifestations, the fetus will become larger and more obvious over time.

At 7 weeks of pregnancy, the fetus is developing rapidly and pleasantly this week. At this time, the fetus is about 1cm long and weighs about 4g. It has the rudiments of a human being, and its body segments have been fully differentiated. The shapes of the head, body, hands and feet can be distinguished.

The fetus has begun to grow fingers and toes at the ends of its limbs. Although they are still slightly connected, they will slowly separate in the near future. In addition to the development of the limbs, the fetus's brain also begins to become active. The embryo, which is about 1 cm long, has a disproportionate head, and the two cerebral hemispheres inside the head are slowly developing. The teeth and mouth are also busy organizing their own structure. And his little nose will gradually become more prominent.

In addition to major changes in the head, the fetus's internal organs also undergo earth-shaking changes. During this period, the fetus has grown its appendix and pancreas, and its liver is busy producing red blood cells. A section of intestine has also begun to enter the umbilical cord. The thin blood vessels inside have the important responsibility of transporting oxygen and nutrients to the fetus! The fetal heart has also begun to divide into the left atrium and right ventricle, and can begin to beat rhythmically.

At 7 weeks of pregnancy, amniotic fluid has been produced in the amniotic cavity. In order to obtain nutrients from the mother, the fetus's umbilical cord tissue develops rapidly. The embryo and fetal heartbeat can be clearly seen from the B-ultrasound, and the gestational sac occupies about 1/3 of the uterine cavity.

There is another magical thing to tell you. The fetus now has a small tail, like a tadpole. Don’t think that today’s fetuses are monsters! In fact, the tail is an extension of the fetus's coccyx and will disappear without a trace after a few weeks. Don’t you suddenly feel that life is a very magical thing?
