traylee01, have you had an internal ultrasound? They should definitely be able to tell from that. If you have pcos you will most likely have too many follicles and then they will run some more blood tests to confirm.
I have pcos and have irregular cycles and light AF too. But my O pains aren't bad at all, only when I take fertility drugs.

If you are considering TTC I would book in to see a specialist ASAP as these things can take time. Good luck
