Any success stories?

Finished taking letrozole a few days ago and had 5mg from day 3 to 7. Have an ultrasound Sunday to see where im at and then have a hcg shot they are giving me. Depending what they say Sunday I then am scheduled for an <a href="https://glowing.com/glow-fertility-program">iui</a>. Anyone have any success stories using this method? I am extremely nervous and trying not to get my hopes up.
