hi iv got PCOS and have been on provera. It has 2 uses, either to stop a heavy period or to start one. I had it a few months ago to start a period and it started all right!! I had AF for 2 and a half months. They are known as my bit*h pills by DH and my friends so good luck wiith it. Iv never had a laporoscopy before but its just a key hole proceedure which isnt so bad.
Good luck with it all
