TTC with PCOS for almost a year now!

I've been TTC for almost a year now since February and my man and I have intercourse all the time, especially when I'm most fertile. It's been frustrating and I don't think I'll be able to conceive! It's sad and worries me. :-( I'm 22 years old with PCOS, of child-bearing age, but I can't seem to get pregnant the more sex we have! Am I not ovulating or something? How bad can PCOS be?!  I really want to conceive! Any ladies with PCOS or a similar experience to mine?
