Has Clomid worked when Femara didn't ?

Hi ladies, I'm so down in the dumps 😞 I was on Letrozole(Femara) 5mg CD 2-9 & follicles didn't mature enough so GYN had me take Follistim injections CD 10-14 (got 2 good follicles) for my last <a href="https://glowing.com/glow-fertility-program">IUI</a>, which didn't work. My first <a href="https://glowing.com/glow-fertility-program">IUI</a> was ectopic. It turns out that I've become resistant to Letrozole now, and my ovaries aren't responding at all.

I've been prescribed Clomid 100mg next cycle. If Clomid fails I'll be onto Follistim injections

, which I'm dreading! What I want to know is has anyone had success with Clomid where Letrozole failed?

I'm 5'3 & 154lbs, don't ovulate on my own at all 😞
