Abdominal pain. The abdominal pain is paroxysmal, the pain lasts longer and longer, the interval is shorter and shorter, and the abdominal pain is relieved after the gestational sac is expelled. 3. Patients have obvious feeling of anal swelling and the feeling of wanting to relieve the bowel movement. When patients force to relieve the bowel movement, the pregnancy sac can be expelled. The medical abortion should be performed under the supervision of a doctor, and the patient can leave the hospital only after making sure that the pregnancy capsule is completely expelled. In case of heavy vaginal bleeding, the intrauterine tissues should be removed immediately and the uterus should be injected with a pro-uterine contraction substance and the ultrasound should be reviewed regularly after the procedure.
