I'm 9 days post IUI today, and IUI was timed to coincide with ovulation after the trigger shot. So tomorrow would be like 10 DPO which is the earliest you could expect a positive. I am NOT the type of person who does well emotionally testing early and getting negatives - much easier to wait it out. I am trying to wait until Sunday which would be 14 days post IUI. I suppose Monday is the day AF would be due. The doctor's office told me to call if I didn't get AF. But if I can't stand waiting I might test earlier than Sunday.
