Feeling unsure

I did my

IUI

this time on letrozole and an injection of ovidrel. I experienced a lot of pain in my ovary since 3 eggs ovulated. Had the

IUI

on Aug 18th. Apparently my cervix entryway is small so he had to pull on it to thread the catheter. That was fun. He finally got it through hitting the top of my uterus another ouchie. But at least it got done. I've ways been super regular and I was due yesterday with no period. I'm not having any of my normal period symptoms, and all the pregnancy tests I've taken are negative. Has anyone else experienced this after being on all those medications?
