We always say that mothers are great because a baby develops from a fertilized egg and stays in their mother's womb for almost ten months. During this period, mothers must endure the discomfort caused by pregnancy. During pregnancy, we need to assess the physical condition of both the mother and the baby through various examinations and indicator data. Let's learn about the normal range of gestational sac size at 70 days.
According to the general rule, the size of the gestational sac should be less than 3 centimeters from 50 days to 3 months of pregnancy; After 5 months of pregnancy, the size of the gestational sac matches the month of pregnancy, which means that at 28 weeks and 7 months of pregnancy, the size of the gestational sac is about 7 centimeters, at 32 weeks it is about 8 centimeters, and so on. At 70 days of pregnancy, the size of the gestational sac is usually about 7 centimeters.
At around two months of pregnancy, the fetus's heart begins to beat. The diameter of the gestational sac is about 2-3 centimeters, and the weight of the gestational sac is about 4-5 grams. The surrounding villous tissue gradually develops to form the placenta. The uterus has slightly enlarged to the size of an egg. The height of the uterine fundus is about 10 centimeters, and the amount of amniotic fluid is about 20 centimeters. The bladder is compressed by the enlargement of the uterus, resulting in frequent urination. There is still no significant change in the appearance of the abdomen, and the lower abdomen is slightly protruding.
At 70 days of pregnancy, it is still around 10 weeks of pregnancy. The fetus has grown to 2.83 centimeters, and all organs of the fetus have formed, forming the embryonic form of the placenta. Ultrasound shows that the gestational sac is beginning to disappear, the crescent shaped placenta is visible, and the fetus is active in the amniotic fluid.
At 9 weeks of pregnancy: The fetus grows to 2.15 centimeters, with the fetal head larger than the fetal body and clearer manifestations in various parts. The head begins to calcify and the placenta begins to develop. Ultrasound shows that the gestational sac almost occupies the uterine cavity, the fetal contour is clearer, and the placenta begins to appear. At 11 weeks of pregnancy, the fetus grows to 3.62 centimeters, and various organs of the fetus further develop, including the development of the placenta. Ultrasound shows complete disappearance of the gestational sac and clear visibility of the placenta.
Through the above content, I believe everyone has gained a deeper understanding of the size of the gestational sac at 70 days of pregnancy. During pregnancy, expectant mothers should pay attention to their nutrient intake, and eating small and frequent meals is a very good dietary habit. The editor suggests that expectant mothers should not be afraid that sports will harm their babies. Instead, appropriate exercise is very beneficial for the mother's body.
