Patient's question:
B cannot detect fetal heartbeat, and the embryo is not developing fully. What are the reasons for this result? What precautions should be noted in the future?Doctor's answer:
Gestational sac stopped growing at 35 days of pregnancy, and an ultrasound can visualize the gestational sac within the uterine cavity. At 6 weeks of pregnancy, the diameter of the gestational sac is approximately 2 centimeters, and at 10 weeks, it is about 5 centimeters. A round, elliptical, and clear gestational sac is considered normal. Currently, there is no research on whether an underdeveloped gestational sac affects the fetus, which may be due to the short duration of pregnancy. If there is no hereditary genetic disease in the family, and the patient does not smoke or experience passive smoking, it is generally not likely to affect the fetus.The first three months of pregnancy are considered the early stage. During the early stage of pregnancy, it is not advisable to expose oneself to radiation or similar substances, as there is a risk of teratogenesis.
