I can't believe they are putting you on the pill. That seems like the FURTHEST thing from a solution, and IMO it will just make it that much harder to conceive. Even among women who don't have PCOS, it can be 6 months after coming off the pill before they can conceive!
What about Vitex? It's natural and supposed to help make things more regular. I've never taken it but have read forum posts about it. A friend of mine took it post-conception (no trouble conceiving, but trouble sustaining pregnancies) after suffering 2 m/c and went on to have a healthy baby girl. It is supposed to be a natural progesterone regulator that helps luteal phase defects and overall hormone levels.
