Patient's question:
My wife has been pregnant for one and a half months. Due to the recurrence of threatened miscarriage, she is currently undergoing bed rest. She has already had two ultrasound examinations, but there is still no fetal heartbeat. Is it harmful to the fetus to have another ultrasound? Why hasn't there been a fetal heartbeat yet?Doctor's answer:
B has little interference on the growth and development of the embryo, but with threatened miscarriage and no fetal heartbeat so far, it is better not to continue if there is a possibility, as such a baby may have the potential for abnormal growth and development. The absence of fetal heartbeat vibrations likely means that the baby has already stopped growing and developing. It may be worth waiting for a closer observation, but if there is still no heartbeat, measures for induced abortion may be necessary. MRI examination does not use radiation and will not cause significant harm to the child.
