IUI round 3

Erica
First <a href="https://glowing.com/glow-fertility-program">IUI</a> was with 50mg Clomid and Provera suppository.
Second <a href="https://glowing.com/glow-fertility-program">IUI</a> 100mg Clomid.
This time I did Letrozole 5mg.
I've noticed very little symptoms. With Clomid I had every symptom in the book. 
What symptoms have you guys had on Letrozole? 
My blood test is on 7/28, keep your fingers crossed!
