6 months TTC

I'm 25, my husband is 37. We've been ttc for 6 months. I used opks every month basically from end of one period until the start of my next. I never got a positive ovulation test. I went to my obgyn and told them we'd been trying, and they suggested getting bloodwork. The bloodwork showed I was indeed not ovulating. He prescribed provera and letrozole. I'm so excited and I really just need my period to start, so I can take the letrozole. I hope September is our month.
