Clomid 1st Cycle Success?

Hello ladies I have PCOS and my cycles are very irregular. I just finished Provera 4 days ago  and AF has showed up. So I start Clomid 50 mg on cycle day 5-9. Do any of you ladies have any success stories. I am anxious and excited. I hope it works on the 1st try. My bf and I have been TTC for 2 years now.
