Letrozole without IUI

Kristen
Has anyone has success with Letrozole without an <a href="https://glowing.com/glow-fertility-program">IUI</a>? My doctor has us trying every other day, day 13 ultrasound showed 19mm follicule so they gave me the trigger shot, but we're trying it without <a href="https://glowing.com/glow-fertility-program">IUI</a>. Any hope!?
