The more prepared that you go to a doctor the better. Right now, I would be more concerned with not having a period in over a year. The uterus lining needs to shed at least every three months. If it doesn't this increases your chances of uterine cancer. So please go get that checked out.
Some women have cysts on their ovaries.
Although the name is Polycystic Ovarian Syndrome, you don't have to have cysts on the ovaries to have it. If you would like to talk about it sometime, just e-mail me. I will help if I can. I am 25 yrs old and was diagnosed with PCOS about 3 years ago. As of this Spring I decided to start to lose weight.
