IUI-have you had one?

Kristy
Hi ladies,
 DH and I went to UAB for a fertility referral yesterday. I've had three rounds of Clomid with no luck. I had surgery in December where they had to remove one of my tubes bc it was detached. The specialist said its time to try letrosol (I think I spelled it right) and do the trigger shot (bc I don't ovulate regularly) and then do the <a href="https://glowing.com/glow-fertility-program">IUI</a>. Has anyone had this? Did it work? Was it uncomfortable? Thanks in advance!
