IUI & Clomid

I have now done two rounds of

IUI

and taking clomid. Has anyone had any success with just doing the

IUI

and Clomid and no trigger shot? I have yet to do a trigger shot with either round. I am still in my two week wait before I can take a pregnancy test, I did take one this morning that was negative. My husband has had a semen analysis and everything was fine. I've gone through testing and there were no issues, yet we still aren't pregnant. I did find out I have a tilted uterus. Any advice, words of wisdom?
