Progesterone and a BFP

Veronica
Hey ladies! My husband I have have been ttc for 2 years now. I was diagnosed with endo a year ago. My Dr. is starting me on progesterone starting 48 hours after peak ovulation test and Letrozole starting on days 3-7 of my cycle. Have any of you ladies had any luck conceiving with either of these?! Thanks! Baby dust to all!
