The small test tube embryo can be called a "fetal baby". His (her) fetal length is about 0.4~1.2cm1.2cm, the fetal weight is about 2.5~6g, and it looks like a dried longan. The organs have already begun to show noticeable characteristics, with small amounts of webbed material appearing between the fingers and toes. 5 weeks of pregnancy: The fetus grows to about 0.4cm and enters the test tube embryo stage. The amniotic cavity expands, initial cardiovascular and cerebrovascular diseases appear, and heart beats may be present. B-ultrasound can show a small gestational sac, which occupies less than 1/4 of the uterine cavity, or the embryonic bud and fetal heartbeat can be seen from it. 6 weeks of pregnancy: The fetus is around 0.6cm. 7 weeks of pregnancy: The fetus grows to 1cm, the test tube embryo has a human prototype, and all the body segments have divided. B-ultrasound clearly shows the embryo, fetal heart rate and fetal heart rate. The gestational sac occupies about 1/3 of the uterine cavity. 8 weeks pregnant: The baby is now about 1.2cm long and weighs about 6g, which is roughly the size of a string bean. B-ultrasound shows that the gestational sac occupies about 1/2 of the uterine cavity, the shape of the fetus and the fetal movement are clearly visible, and the yolk sac can also be seen. By now the baby's organs have begun to show noticeable characteristics. There are small amounts of webbed tissue between the fingers and toes, and he (she) has begun to move like trembling soybeans. At the end of the second month of pregnancy, the baby's head and body contours can be identified, the tail has become smaller, the eyes, ears, and lips are roughly formed, and the contour of the face is already formed, but the eyes are still on both sides, and the bones are still in cartilage state. The heart, liver and other internal organs have long been perfected, the human brain is growing and developing rapidly, and there is amniotic fluid in the amniotic cavity, and the fetus seems to be floating on it. At this time, the connection between the pregnant mother and the fetus is more inseparable. Your current appearance has not changed much. But you may notice that your bra is tighter, and soon you may need to wear a larger bra than before to better support your breasts. This is because the increase in estrogen in the body causes the breasts to enlarge, and other tissues are also changing, all in preparation for breastfeeding. In addition, you may experience early pregnancy reactions such as dizziness, constant sleepiness, nausea and vomiting. You may now be going to the bathroom more often and more frequently than usual because your uterus is growing and pressing against your bladder. You may feel tired and sleepy all the time, and nausea and vomiting will naturally drain your energy. If possible, try to sleep 9-10 hours at night, or take a nap during the day. |
