As

i’m currently on my first round of letrozole (2 pills a day) and on 1500mg of metformin. we are supposed to also do a trigger shot this month and an <a href="https://glowing.com/glow-fertility-program">iui</a>. has anybody had success on their first month or did it take multiple times for you to become pregnant? we used clomid for year (3 pills a day) and had no success so i’m wondering if other people had better luck with the letrozole instead of clomid?
