There is still hope even at eight weeks of pregnancy without a fetal heartbeat, but there will be individual differences. The duration of pregnancy is affected by the menstrual cycle, the time of ovulation and the time of fertilization of the egg, etc. The intrauterine gestational sac can be seen on ultrasound at 5 weeks of pregnancy, which can clarify the pregnancy. At 6 weeks of pregnancy, ultrasonography can see fetal buds and fetal heartbeat. However, for long menstrual cycles, the appearance of the fetal heart will be delayed, so there is still hope when there is no fetal heart at 8 weeks of pregnancy, you can follow the doctor’s advice about 1 week to review. In early pregnancy, when you see intrauterine fetal buds on ultrasound, you can also combine the size of the fetal buds with the progesterone and blood HCG (human chorionic gonadotropin) levels to estimate the week of pregnancy. When there is a dysplasia of the embryo, you can follow the doctor’s instructions to give progesterone, low molecular heparin and other drugs to keep the fetus in labor, and repeat the examination on a regular basis. When there is no fetal heartbeat at 8 weeks of pregnancy, observation and rechecking can be carried out as prescribed by the doctor.
