What does a pregnant woman's three-month fetus look like? Three months of pregnancy is the initial stage of pregnancy. At this time, actually, my mother's stomach is not very big. So do you want to know what the fetal picture looks like after three months of pregnancy? That is, from the 9th-12nd week of pregnancy. In week 12, the fetus is in a period of all-round and rapid development. The development of fetal skeletal cells is accelerated, the limbs are gradually lengthened, the fingers of the limbs are clearly visible, the bones are hardened, and the head is particularly large, accounting for half of the body length alone. The heart, liver, gastrointestinal tract are more developed, and the kidneys are also developed.
This week is a period of full and rapid development of the fetus. The development of fetal skeletal cells is accelerated, the limbs are slowly lengthened, the tips of the limbs are clearly visible, the bones are hardened, and the head is particularly large, accounting for half of the body length alone. The heart, liver, gastrointestinal tract are more developed, the kidneys are also developed, and the ureter has been formed. The fetal heartbeat can be heard by the fetal sound device. At the end of this week, the sex of the baby can be identified.
The real critical moment of the baby's growth is coming. By the end of this week, the new body structure will be fully formed. The joint activities of head, neck, trunk and limbs are more obvious, indicating that the neuromuscular coordination system has been established. At this time, the placenta is basically formed, and the connection between the fetus and the mother has entered a stage of steady development, and the chance of miscarriage has decreased accordingly. The fetus has begun to enter the stage of rapid proliferation of brain cells.
Three months of pregnancy is an important period for pregnant women. Some basic organs of the fetus have gradually formed, but because the movements of the fetus are still not strong enough, they cannot be felt for the time being. So how much does the fetus weigh after three months of pregnancy? Let's take a look at it together.
1, the first three weeks of pregnancy, that is, the ninth week of pregnancy, when the fetal size is about 25mm, many parts of the fetus have changed, such as the head, arms and legs, reproductive organs and other parts have changed. In contrast, the third month of pregnancy will increase a little.
2. In the second week, the fetus can reach 40 mm in size and is shaped like a flat pod. This week, the development of the fetus and ankle joint has been completed and clearly visible, as have other parts of the baby. The eyelids of the fetus are stuck together, and the blood of the fetus is very mature.
3. In the third week, the fetal size can reach 40-60mm, and the fetal weight can reach about14g. From this week, the baby's growth rate will become more and more obvious. From now on, pregnant mothers don't have to worry too much about abortion. Now the baby's fingers and toes are also clearly visible.
4, the fourth week, the fetal volume can reach 65mm, this week all the baby's trachea began to work, such as the liver began to secrete bile. The kidneys excrete urine into the bladder. Then in the last three months of pregnancy, the fetal volume will grow to about 75mm, and the fetal weight will increase. This month, when B can still see the fetal movement, the pregnant mother really can't feel it.
