Letrozole success 5mg?

Fen

Hello! My husband and I have been trying for 15 months for our 2nd. I have regular periods and ovulate naturally and all of our tests have come back completely normal. My OB started me on a medicated cycle with 5mg Letrozole (Femara) for 5 days CD 3-7. Wondering if anyone who has regular periods and ovulates normally had success with Letrozole.

Thanks!
