Experience with ovulation assistance drugs?

My husband (39m) and I (28ftm) have been trying to get pregnant since September. I stopped T in May of last year and still haven't had a cycle, so I went to get checked out in December. Turns out after some testing that I have PCOS and the doctor suggested that I try ovulation assistance. We tried a round of Clomid at the end of December, after my progesterone check it shows that I didn't ovulate. We're increasing the dose of Clomid this time around, if that doesn't work then we're considering trying Letrozole.

Does anyone have experience with ovulation assistance drugs? I'm really hoping that it works, preferably without having to go through lots of cycles. I'm trying not to get discouraged by statistics. Thanks!
