Women who have a medical abortion will begin to experience pain 2-6 hours after the application of the medication and the pain will gradually diminish after the gestational sac is expelled. A medication abortion is usually performed by oral misoprostol tablets or vaginal insertion of carboprost suppositories, which softens the cervix and also promotes contraction of the uterus, making it easier to expel the embryonic tissue. The pain is usually caused when the endometrium starts to shed around 2 hours after the application of the medication, i.e. contraction pain. However, the duration of abdominal pain varies from person to person, with the earliest onset of symptoms often occurring in 1-2 hours and the slowest may take 4-6 hours, sometimes accompanied by vaginal bleeding. The pain will gradually diminish as the uterus contracts to induce the expulsion of the embryonic tissue, and the pain will be relieved by itself as the uterus is reset after complete expulsion. After the abortion, pay attention to keep warm, avoid getting cold, avoid eating cold, spicy, hard and irritating food, and follow the doctor’s prescription to promote the discharge of blood and uterine regeneration. After the abortion, it is forbidden to have sexual intercourse for one month, pay attention to rest and avoid overexertion. 7 days later, it is necessary to confirm whether the embryonic tissues in the uterus are completely discharged by ultrasound examination, and if there are residues in the uterus, it is necessary to carry out the operation to clear the uterus in time, so as to avoid the infection of the residues and inflammation in the uterus.
