Those with PCOS

How did you find out? I used to be super regular, then got on birth control when I was 18/19. Got off when I was 21 and then immidiatly got pregnant (was a surprise and we used  protection) . I got back on birth control and then got off again in December of 2013. Had two regular periods January and February. Then in march I had a chemical pregnancy and it seems ever since then I won't have a period. My doctor seems to think I'm not ovulating. May 7th I had a period induced by provera. I used opk while I was on that provera period and I got a positive. Then a week and a half later I used an opk again and got two dark lines but not quite positive, but the next two days the test line would get lighter like I had already ovulated. Then, on June 2, I got a way positive opk and the. They would get lighter each day after. So my question is, did I try to ovulate 3 times? And with so many positives is that a symptom of PCOS? How can you tell if you really ovulated? I took a pregnancy test two days ago and it was negative. Just sucks cuz I've been cramping, nipples are getting sore and I just feel so crappy. No sign of my period either. Anyone have any words of wisdom?? It would be much appreciated!! :)
