Hello, I'm 29 yrs old, married for 6yrs. Trying to conceive. I have PCOD, periods are irregular. had IUI done twice. Right now i am taking MR.Met 500 twice a day and duphaston. I have been taking duphaston for about eight months now since 18th day of ma period for 7 days. i want to know will it have side effects or any harm in having it to get regular periods. And any why MR Met 500 as i found that it is a tablet given to diabetic patients, and i am not diabetic.
