What are the reasons for increased menstrual flow after medication abortion?

Patient's question:

Medication abortion check ultrasound is clean now I have my period but it's normal period is more and this morning it was less then it got more is it normal what could be the reason

Doctor's answer:

Under normal circumstances, menstruation can return approximately one month after a miscarriage. However, for those whose hormone levels have not fully returned to normal after a miscarriage, experiencing irregular menstrual cycles—such as delayed periods, varying cycle lengths, or changes in menstrual flow (either heavier or lighter)—is also normal. If such symptoms reappear, it typically takes about 2-3 cycles for menstruation to gradually return to normal. Please continue to monitor your condition for a while longer. Wishing the patient a speedy recovery!
