PCOS symptoms?

My doctor thinks I might have PCOS because I've skipped my period every month for the past 4 months... Even if I take provera, I skip the next. I don't ovulate. Ladies, what were your PCOS symptoms? I'm feeling down from this news... I have blood work and an ultrasound scheduled for next month if I don't get my period. Please tell me what symptoms you experienced/are still experiencing. TIA.
