The development process of a baby is from the fertilized egg to the embryo and then to the fetus. Without the formation of the embryo, there cannot be a normal fetus, so pregnant women should pay attention to the development of the embryo. So how big should the fetus be at 51 days pregnant?
At 51 days of pregnancy, the normal size of the fetal bud is 6mm, and at this time, the heartbeat of the fetus can be seen. Generally, the fetal buds are relatively small on the 50th day of pregnancy, and it takes about 60 days to see obvious fetal buds. The appearance of fetal buds in each pregnant woman is different. Some pregnant women usually ovulate later and the fertilized egg implants later, so the appearance of fetal buds is delayed. Women don't need to worry too much.
The content of progesterone is closely related to the growth of fetal buds. By 5-6 weeks of pregnancy, some pregnant women can already observe the gestational sac, and in the following one to two weeks, fetal pressure can be seen developing and growing. So pregnant women should regularly undergo prenatal check ups to ensure the safe development of the fetus. Through B-ultrasound examination, as long as the fetal heart beats, it proves that the embryo is developing well.
The size of fetal pressure can only be determined through B-ultrasound examination. It is recommended that pregnant women pay attention to their diet in the early stages of pregnancy, eat some folic acid tablets appropriately, and do a good job in prenatal care and prenatal check ups; At the same time, it is important to pay attention to rest as the fetus is still unstable in the early stages, so pregnant women should avoid overexertion.
