PCOS and pregnancy

So I have PCOS and my doctor recently put me on Metformin 2000mg a day and Adipex. For the first time in 10 years I have had regular periods! Yay! My husband and I are trying to conceive. So far I have lost 10lbs which is huge for me and my PCOS struggles. I was wondering has anyone else had success with this kind of treatment? I fear it is something that just won't happen for me. I kind of made amends with this when I was younger but my husband is wanting a baby so bad. Has anyone had success with this without having to do fertility drugs?
