I have the problem of P.C.O.D. (polycystic Ovaries Disorder) and my periods are irregular, since last two months i didn t had my cycle, Dr. prescribed my Sandoz Regestrone 5 mg, and Surbex XT for 10 days. For Sandoz Regestrone i am supposed to take twice a day, and for Surbex XT once a day. But because of my irregularity in periods it s affecting my skin bad, my face is full of blemishes. Are these medicines going to work bring my cycle, because it s been 7 days already and i still don t feel any signs.
