IUI (Letrozole and HcG trigger shot)

Ki

I will have my first <a href="https://glowing.com/glow-fertility-program">IUI</a> next week! Dr prescribed 5mg of Letrozole for 5 days. Then ultrasound and Trigger shot before <a href="https://glowing.com/glow-fertility-program">IUI</a>.

I had a miscarriage in September. I passed all the test unimaginable and everything is normal for me and my SO. I guess we are just old so that’s why it’s so long to conceive.. lol

I wonder why I need the Letrozole and trigger shot even if I ovulate naturally. I did research and I see it helps ovulating... ok. But it must do more since I already ovulate? Does it help with quality of the egg or eggs? Do you know?

Thanks in advance !
