There is no clinically most effective method of spontaneous abortion. The main methods of pregnancy termination are currently abortion and medication abortion. The main types of medication abortion used are mifepristone and misoprostol. On days 1 and 2, it is oral mifepristone. The first time you take it, you take 50mg at 6am and 25mg at 6pm, and you take it the same way on day 2. On day 3, you can take Misoprostol orally at 6:00 am. When taking these two medications, you should not eat for 2 hours before and after to avoid reducing the effectiveness of the medication. After 3-6 hours of taking Misoprostol by mouth, the gestational sac may be expelled from the body and sometimes the bleeding is quite heavy. Therefore, when taking the last 3 tablets of Misoprostol, it is important to go to the hospital and apply it under the close observation of the doctor to avoid heavy bleeding. If the bleeding is heavy, it is always necessary to clear the uterus to stop the bleeding.
