Letrozole vs clomid

M&M

Hello everyone. I’ve tried clomid last year and conceived on the third cycle but had a miscarriage at 10 weeks. I was told later by a fertility specialist that clomid actually thins the uterus and can cause miscarriage. I’d like to try letrozole. Has anyone taken letrozole and been successful? If so, what dosage were you on and how long did it take?
