How long does it take for menstruation to come after medical abortion?

The use of anti-estrogen drugs to stop early pregnancy can be used for those who have a fear of abortion surgery within 49 days of pregnancy, or those who require medical abortion. Medical abortion is prohibited for patients with severe cardiovascular and cerebrovascular diseases, respiratory, digestive, kidney, blood, endocrine, urinary system, reproductive system or central nervous system diseases, adrenal diseases, endocrine-related tumors, diabetes and other endocrine diseases, abnormal liver function, heart disease, glaucoma, gastrointestinal disorders, anemia, hypertension, asthma, allergic constitution, severe vomiting during pregnancy and with IUD insertion, or suspected ectopic pregnancy.

Medical abortion has significant disadvantages: longer bleeding time and sometimes high incidence of tissue residue. Patients with a high risk of tissue residue after medical abortion need uterine curettage, so medical abortion must be performed in a hospital with emergency room, curettage, intravenous drip, and injection conditions, and should be monitored and used under the guidance of a physician with certain experience. Medical abortion requires such a rigorous process, so how long will it take for menstruation to come after medical abortion?

Normally, the uterus and ovaries can resume ovulation function within 22 days after medical abortion, and menstruation will occur within about 1 month to 40 days. However, a very small number of women experience menstrual disorders such as prolonged menstruation, irregular cycle duration, and amenorrhea after taking the medicine. This condition usually recovers after 2-3 months, but in a few people it lasts longer.

However, it is possible that the menstrual period is delayed after medical abortion. The main reason is that the decidual tissue cannot be completely discharged after medical abortion, resulting in prolonged bleeding. A large number of patients eventually need to undergo a curettage, which increases the chance of genital infection and causes menstrual disorders. Because abortion drugs can cause irregular menstruation, early or delayed menstruation, and prolonged menstruation. In addition, if menstruation continues for one month after medical abortion, infection, residual residue in the uterine cavity and hormonal disorder in the body should be considered.

However, if menstruation is delayed after medical abortion, in addition to the reasons for medical abortion, other causes of amenorrhea should also be considered. If you had menstruation before and then stopped for 3 months or more, it is secondary amenorrhea. Diseases in the uterus, ovaries, pituitary gland, hypothalamus and pituitary gland may cause secondary amenorrhea.
