Under normal circumstances, germs will appear around 40 days of pregnancy, and fetal heart can also be found at 7-8 weeks of pregnancy. However, some pregnant women have a late fetal heart rate, so it is recommended to check again in a week or so. If a woman is pregnant and still has no fetal heart rate, it is considered that it may be fetal arrest. It is recommended to check HCG. If the values of HCG and progesterone keep decreasing, it can be diagnosed as fetal arrest. If we continue to wait, there is no hope, and surgery is needed to end the pregnancy.
Pregnant women with normal pregnancy should know that fetal heart and embryonic buds do not develop at the same time, and the time when fetal heart appears is later than that when embryonic buds appear. However, most cases of embryonic buds without fetal heart after 60 days of pregnancy are abnormal, suggesting that the embryo is likely to stop developing, but some pregnant women do not want to give up. At this time, the doctor will recommend a review in a week. At this time, if there is still no fetal heart, it is necessary to consider abortion as soon as possible.
In a word, fetal heart rate is the basis for judging whether fetal development is healthy or not. Pregnant women should pay attention. After a certain period of time, the fetal heart can not be seen, indicating that the fetus has not continued to grow and develop. In order to avoid the serious impact of fetal detention on pregnant women's health, it is very important to terminate pregnancy as soon as possible.
