Are you checking for signs of ovulation? Using the opk's or checking cervical mucus? Even if these signs are positive, once in a while, an egg will just sort of get stuck in its little sack and not release and cause a small cyst. The cysts from that are usually very small and not real painful. If you are truly having a lot of pain, you need to contact your doc.
Most obgyns make you try for 6 months on your own before they start fertility work-ups, unless you are older than they may start sooner.
Unless you are being monitored, having blood work and ultrasounds, there is no sure fire way you can tell that you actually released an egg despite having a positive opk or good cm.
PCOS can be very serious but if this is the first time you have had a cyst, its unlikely the cause but as I said, if it really hurts, call, don't wait.
I went through the whole fertility thing, everything but IVF and that was due to money and the fact that I could get pregnant, it just took time but my problem was that I could not carry the pregnancy. They now believe I have some clotting problems despite all my clotting tests coming back negative. I am currently being treated for 5 blood clots and at the time the clots were discovered, my clotting factors still showed negative!
