I was recently diagnosed with the samething... Im still kinda new at learning about it too, but you should talk to you doctor about your options. I was told there are a few things that can be done. It all depends on if you want to have children or not. If you dont want children anytime soon, you could get on birthcontrol pills and it will straighten out your hormones and you should then get your monthly periods... If your trying to concive then you can get medications to make you ovulate and it should increase your chance of conception. Like i said you should go over your options with you doctor!
pcos in my opinion dosnt start off with a major problem but can lead to many major problems. If you alredy havnt you should get some information about it and read up and go back to your doctor! Good luck with everything!
