Whether or not to keep the pregnancy without yolk sac depends on the week of pregnancy, when the pregnancy is about 5 weeks, you can follow the doctor’s advice to review, but there is still no need to keep the pregnancy at 8 weeks of pregnancy. For women with regular menstrual cycles, the earliest time to see the pregnancy sac and yolk sac in the uterine cavity is at 5 weeks after menopause. If there is no yolk sac at this time, it may be due to the long menstrual cycle, etc., so it can be observed temporarily and rechecked after 1 week according to the doctor’s advice. However, when there is no yolk sac at 8 weeks of pregnancy, it can be suggested that the embryo has stopped, there is no need to keep the fetus, and it is necessary to terminate the pregnancy in a timely manner.
