After the fertilized egg successfully implants in the mother's uterine cavity, it will continue to grow and develop, leading to the appearance of gestational sac, fetal heart, fetal bud, etc. If no fetal heart or bud is found, it should be taken seriously. It may be due to abnormalities in the embryonic development process. Some mothers have asked whether it is normal to have no fetal heart or bud at 50 days of pregnancy?
In general, the formation time of the gestational sac is about thirty to forty days after the embryo becomes pregnant, the formation time of the fetal bud is about forty to fifty days after the embryo becomes pregnant, and the formation time of the fetal heart is about fifty to sixty days after the embryo becomes pregnant. Therefore, if the fetal heart and bud are not detected after fifty days of pregnancy, two possibilities should be considered. The first is that the ovulation period is delayed and the pregnancy time is short, so it cannot be detected temporarily. The second is that the embryo has stopped developing.
When this situation occurs, doctors will recommend that the pregnant mother go to the hospital for a B-ultrasound follow-up ten days later. If the fetal bud and heart rate have already appeared, the pregnancy can continue. However, if the fetal bud and heart rate still have not appeared, it is necessary to consider that the embryo has stopped developing and terminate the pregnancy as soon as possible to avoid adverse effects on the mother's physical and mental health.
Due to the varying rates of embryonic development, some embryos may develop rapidly in the early stages and then slow down in the later stages, while others may develop rapidly in the later stages. Therefore, when an embryo develops slowly, there is no need to worry too much for now. As long as the embryo can eventually form a fetal bud and heart during development, it proves that the embryo is a live fetus and developing normally.
