The majority of abortions are performed within 6 hours of taking the second pill, and some women expel the gestational sac within 1 week afterwards. In rare cases, the gestational sac is expelled during the oral administration of mifepristone, mainly in women with low progesterone levels or in women who have undergone fetal abortion. If you do not see the gestational sac expelled within a short period of time after taking mifepristone, you should not be too anxious and observe the amount of vaginal bleeding first. If the vaginal bleeding is low and the abdominal symptoms are not serious, you can observe for about 1 week and review the pelvic ultrasound after 1 week. If the vaginal bleeding is heavy, but there is no tissue discharge of the pregnancy capsule, it may cause blood loss anemia and requires immediate removal of the uterus. In addition, medical abortion is suitable for healthy women within 49 days and under 40 years old. Before abortion, women need to determine intrauterine pregnancy by ultrasound, then undergo physical examination and blood test, and must take the medication under the guidance of a professional doctor if there are no contraindications.
