Anyone get pregnant with Letrozole 7.5 mg?

I’m just curious if anyone took the 7.5 mg and was successful with their <a href="https://glowing.com/glow-fertility-program">IUI</a>.

I did 3 rounds of 5 mg of Letrozole. Now the doctor increased it to 7.5 mg.

This will be my 4th <a href="https://glowing.com/glow-fertility-program">IUI</a>. Hope it will work.
