In the early stages of pregnancy, mothers are more concerned about the formation of fetal buds and fetal heart during prenatal checkups. With fetal buds and fetal heart, it can be preliminarily judged that the embryo is healthy at this time. Some mothers are already 50 days pregnant, but there is a problem of hidden embryo without fetal heart. Is this situation normal?
This situation is normal.
The process of embryonic development is as follows: the first 30 to 40 days after pregnancy are the time for the formation of the gestational sac; The embryonic buds form between 40 and 50 days; The fetal heart rate will gradually form between 50 and 60 days. Therefore, it is more appropriate to have a B-ultrasound around 60 days of pregnancy, because at this time, it can observe whether the gestational sac, fetal bud, and fetal heart rate are normal from the B-ultrasound.
However, after pregnancy, some mothers may have a slightly delayed implantation of the fertilized egg, or the development of the fertilized egg after implantation may be slower, so the fetal heart rate may also appear later, but it will fully appear before 20 weeks of pregnancy at the latest.
It is normal to see fetal sprouts without fetal heart rate at 50 days of pregnancy. Mothers can go home and rest assured to continue waiting for the pregnancy. If there are no abnormal symptoms, the early pregnancy reactions do not improve or disappear, and there is no bleeding in the mother's vagina, they can continue to wait for another ultrasound observation at 12 weeks.
It should be reminded that some unhealthy habits in early pregnancy, such as staying up late, not paying attention to diet, etc., may affect the development of fetal heart rate, leading to late onset of fetal heart rate or even fetal arrest. Therefore, expectant mothers must not be careless in all aspects during early pregnancy.
