Hey. I am a 20 year olg girl with irregular (mostly 2 weeeks early),scanty periods, lasting approx 6-7days (with the bleeding stopping at evening, and night afterwards) at the present, first they used to last for approx 4-5 days, then the doctor diagnosing me with PCOS prescribed a medicine in order to check the severity of the syndrome (after which the bleeding time prolonged,as I mentioned earlier, but no other effect), so she suggested me to get the situation tested through hormonal tests, i moved to another doctor,shesuggested that it might be some sort of hormonal imbalance, so she prescribed me a medicine (Glucophage-500mg 2 times a day), alongwith some multivitamins for atleast a month. now wanna know what exactly it could be? possible treatment? extremely worried. :(. waiting anxiously for the reply !!
