I have polycystic ovaries, irregular AF, weight issues (not helped by my love of chocolate LOL!!) but not the syndrome because my hormone and insulin levels are relatively normal. My DH and I were able to conceive without the help of medication but these was our last cycle before Clomid so it is definitely possible. Weight is a really a big thing with PCOS. I am carrying a few extra kilos (approx 8kg then average) and I was told to drop a few to help with conceiving.
Wishing you the best of luck. Let us know how you get on with the dr. Sending heaps of positive vibes your way.
