Whether or not it is normal to have a heavy period after a medication abortion depends on how heavy the period is, if it is just slightly more than the usual amount of menstruation, it is usually normal. Because of the first time to menstruate after a medical abortion, the ovaries have not fully recovered, which may lead to heavy or light menstruation, these are normal. However, if the menstrual flow is particularly heavy, with large blood clots and dribbling, this situation should be considered whether the abortion has not been cleaned up, and there are residual tissues inside the uterine cavity that cause bleeding. You need to go to the hospital to do ultrasound to see if there is any abnormality in the uterine cavity, if there are irregular echoes, you need to do a purging operation, if there is no residual tissue you need to stop the bleeding treatment under the guidance of the doctor.
