IUI scheduled for tomorrow but i already surged

Help!! What should I do? I told nurse and i sensed some frustration from her that I wasn’t trusting the doctor. My last blood work and ultrasound was Monday, and he predicted by Thursday I’d be ready. Well itsWednesday and I’ve surged . What do I do 😪😪😪 so sick of this roller coaster . My first IUI it was done after ovulation too. This can’t help things..,

This is my 3rd one
