i recently had a miscarriage but did not stop bleeding for the next three weeks after that. i went to see a doctor, had a scan and was prescribed some medication. about a week after i took the meds, the bleeding stopped. its been 2months now but yesterday while i was at work started bleeding heavily but i had no sign of a period coming, the blood was thick, red unlike menstrual blood. it was so heavy it even ran down into my shoes. it has since stopped but i am getting worried. what could be the problem?
