It is normal to experience cramping in the abdomen three days after a medical abortion. This can occur due to damage to the endometrium, or due to vaginal bleeding, which will gradually improve in about a week. Under normal circumstances, it takes one week to two weeks to go to the hospital for a follow-up check to see if there is any intrauterine residue. If there is more intrauterine residue, the uterus will need to be cleaned out. During this period of time, you must pay attention to the cleanliness of the vulva, pay attention to warmth, you can apply hot compresses to the abdomen, and must prohibit sexual intercourse and tub baths to avoid infection. If the pain in the abdomen is not relieved or worsened, you should go to the hospital for examination.
