Hi doctor, I myself has been diagnosed with pcod with minute fluid filled follicles. I am not undertaking any medication for pcod. As per my family gynecologist's advice i am taking meprate 10 mg tab every month for periods. But now my periods was normal and it lasted for 5 days. After 8 days i have noticed bleeding again which is thick and deep red colour blood. It is been continuing for 4 days now. Slight back pain is also noted. Could you please reply for my query. What would be the reason for such prolonged bleeding.
