Being 8 weeks pregnant and having an ultrasound with an 8 mm bud and no fetal heartbeat is not a normal phenomenon, and it is likely that the embryo has ceased to exist. For women with regular menstruation, usually after 6 weeks of pregnancy, go to the hospital for ultrasound, not only can you see the gestational sac in the uterine cavity, but also can see the fetal buds and fetal heart tube pulsation. At 8 weeks of pregnancy, the fetal buds are already 8 millimeters, and under normal circumstances, the fetal heart should be able to be seen. If you can’t see the fetal heart now, it is possible that the embryo has stopped. If the embryo has stopped, the level of human chorionic gonadotropin in the body will decrease, and the symptoms of early pregnancy reaction may be relieved on their own, and some patients may experience a small amount of vaginal bleeding. If it is determined that the pregnancy has been terminated, it is necessary to terminate the pregnancy in a timely manner, which can be treated with medication or surgery under the guidance of a doctor.
