The best time for a medication abortion is within 49 days of pregnancy. Misoprostol medication or mifepristone tablets can be used orally to terminate early pregnancy. Both drugs can cause contraction of the uterus or degeneration and necrosis of the uterine metaplasia, softening of the cervix, and promote the effect of embryo expulsion. Medication abortion usually takes 3 to 4 days and requires an ultrasound or related examination at the hospital to determine an intrauterine pregnancy and choose the method according to the size of the embryo. If the embryo is too big, the medication abortion may not be able to be expelled, and the operation to clear the uterus will be needed, so don’t use the medication blindly, it is better to be under the guidance of the doctor. There will be a small amount of vaginal bleeding in the first 2~3 days after abortion, you can observe it first, if the bleeding is very heavy or persistent, you should go to the hospital in time.
