The amount of bleeding after curettage will not exceed the amount of menstruation, but if the bleeding time is too long and the amount of bleeding is high, this may be caused by improper surgery. However, if the bleeding is prolonged and heavy, it may be caused by improper surgery. It may also be caused by damage to the endometrium during the scraping procedure, or it may be caused by intrauterine infection due to lack of hygiene after the surgery.
