i have pcos and have delt with it since i was 18 years old.pcos has alot of factors that can cause serious health issues.high blood pressure and cancers and facial hair or hair growth were women don't grow hair.weight gain all kinds of factors.to help you get your body back on track you need to change your eating habits like stay away from sugars and fatty foods.also excersice will help you.as for me mine is caused mainly from hormone imbalance yours sounds more like yours is from blood sugar pcos can cause diabetis so really look out for what you eat.you also might want to ask your dr.to put you on progesterone because within 7 days or so your period will start then she should try metformin.believe me this will help you.i have been on metformin for 3 years my periods have been regular if you are trying to get pregnant you don't want birth control but if you are not trying to get pregnant you can try birth control.you might have some brownish blood first time when you get your period but it could just be old blood.but i really hope everything works out for you and i hope this helps you
