How many have successfully gotten pregnant from letrozole?

Dene

So I went through one round. I did ovulate so it worked successfully. As for my back story, I wasn't ovulating before. I had no periods for a year . . . so I'm kinda glad I didn't catch this cycle. So everything is back on track now. I'm going on round two. How long have you ladies that have taken letrozole been on it? and have you had any luck? if so how many cycles before you concieved? Sorry! ladies just curious.
