Hi Dr.Samuel, ahve a question in reagrds to Mirena, my first one fell out after 2 years and I had almost 6 months of bleeding at the beginning, now I inserted the new one and the bleeding is even worst, my Doc. prescribed Megestrol 40 mg twice a day, but it seems that it doesnt help or even getting it worst. I see the side effects of the drug as unexpected bleeding...I don t quite understand why the drug for breast cancer patients was prescribed for me?
