Suggest Treatment For Irregular Periods With PCOS

Dear Dr.I am suffering from polycystic ovaries.I have irregular periods and I am also suffering through hirsutism. Its been more than a year since I had a natural period. I used Krimson-35 and I got periods only when I used them. I took it for 3 months and stopped. Its been 4 months and I still didnot get a period. My age is 23 ,My height is 5'4" and my weight is 62kg.Thanks ,Sincerely,Ramya
