During the development of the fertilized egg, the development of the fetal heart and embryo buds is crucial. Once the fetal heart and embryo buds are present, other organs gradually form as well. Pregnant women need to undergo regular prenatal check ups during pregnancy, not only to ensure their health, but also to observe the development of the fetus. So, how many weeks can the fetal heart rate and buds be detected?
After a woman becomes pregnant, the fetal heart and buds can usually be seen through B-ultrasound around 7-8 weeks of gestation. The time of pregnancy usually starts from the first day of the last menstrual period, which may not be synchronized with the actual time of conception.
If the pregnant woman is a normal intrauterine pregnancy, then under normal circumstances, at 42 days of amenorrhea, the fetal heart rate and fetal heartbeat can be clearly seen through ultrasound. However, for some pregnant women, the implantation time of the fertilized egg is relatively late, so the fetal heart and embryo may not be visible yet. For pregnant women who ovulate late and have irregular menstrual cycles, the appearance of fetal heart and fetal sprouts in the uterus may also be delayed, but no later than 56 days. If after 56 days, fetal heart buds and pulsations cannot be seen in the uterus, the possibility of embryo arrest should be considered.
If the fetal heart rate and fetal bud cannot be monitored for a long time, it is necessary to follow the doctor's advice. In the early stages of pregnancy, pregnant women are easily affected by various factors and may experience miscarriage, so it is important to keep the fetus safe in the early stages of pregnancy, as it becomes more stable in the middle of pregnancy. If pregnant women experience symptoms of abdominal pain and vaginal bleeding, there is a high risk of threatened miscarriage.
