PCOS, Provera, and Clomid

Mikaela
I am almost done with 10 days of provera and then will soon be starting 50mg of Clomid. Wanted to know how many women with PCOS this has been successful for? My Doctor said if after three months I don't get pregnant I have to come in for a follow up but I'm worried she will just tell me to loose more weight again.
