The time of medical abortion is usually within 49 days of menopause, and the earlier the best time, the better. Medical abortion is an outpatient gynecological operation and is indicated for the termination of pregnancy within 49 days, i.e., the period from the time the intrauterine gestational sac is seen in the uterus to determine early intrauterine pregnancy to seven weeks of menopause, mainly through oral medication to terminate early pregnancy. Normally, the intrauterine gestational sac can be seen under ultrasound monitoring at about five weeks of menopause. Secondly, the best time for medical abortion varies for each person due to the early and late implantation and the size of the gestational sac, the larger the gestational sac the less effective the medical abortion is. Therefore, the earlier the best time is, the better, when the gestational sac is smaller, the greater the possibility of complete expulsion of the gestational sac, and the less bleeding. In addition, if the patient is more than 7 weeks pregnant and there is a relative contraindication to surgery, she can be hospitalized for a medical abortion if necessary, but she needs to be observed at all times and given surgical treatment if necessary.
