I have both PCOS and endometriosis, both of which can greatly reduce your fertility. Despite that, I have two children. I did not take fertility treatments, and had absolutely no problem getting pregnant. In fact, I told my husband I wanted to have a baby (both times) and we tried once or twice, and then I was pregnant. I'm not kidding! One time! Besides that, I just got off of Depo Provera, and I had an ultrasound, and they found a cyst. Which means I ovulated while on birth control!
So not everyone with PCOS has fertility problems. Maybe my body is just REALLY different from everyone else. Don't give up hope, your body might be different too.
