Menstruation may come early after abortion, this is due to the fact that patients may experience early or delayed menstruation within 3 months after the abortion, the amount of menstruation may be more or less, these are all normal phenomena, but usually the menstruation is early within about 7 days, and delayed as well. If it is too early, it should be suspected that it may not be the onset of menstruation, but may be uterine bleeding. If it is 10 days early, you need to go to the hospital for an ultrasound to see if the inside of the uterine cavity is all cleaned up and if there is any residual embryonic tissue. This is because if there is residual uterine tissue after the abortion, the patient will also experience vaginal bleeding.
