I have irregular periods from the day I got matured and I am 29 now and I am un married, I have been diagnised with pcos and have used severely medications including meprate, regstrone and kris on 35 mg hormone tab for a period of 3-5 months and from past 8 years. When I used the tab I used to get regular periods for 3-4 months even after stopping the tabs, but again after those 3-4 months it's same situation periods were delayed and may not been there even for 90 days, then again I have to go back to medication. This is persistent prob with me. And even this time it's the same case, I have stopped my medication as per doctors advice 6 months back and after that I got my regular periods only for 3 months. Now from past 3 months I Have not got my periods though there are symptoms of periods. How I should I deal with this persistent recurring problem to get permanent cure and regular cycles.
