I really wish I could offer you more advice on this too !
I am seeing an endo. doctor as well. He has put me on Glucophage ( Metformin) to regulate the insulin --which is part of the problem with PCOS. He said that taking this would increase me chances of getting pregnant but so far no luck. Ive tried Clomid before this but it didnt work, just drove me crazy.
My next step would be to go to a fertility clinic for the next treatment.
Good Luck to you. I will keep updating with any info. that I get. Please do the same if you learn of anything new.
