IUI HELP!

Okay so I’m doing my 9th IUI but first with my new dr 🤞🏼 so I started with 3 days of 75 gonal-f and first ultrasound showed nothing so I’ve been doing 200 for the past 6 days, including tonight which is my last night, ultrasound tomorrow to check follicles. So anyway, I took an ovulation test just now for S and Gs and got this! Wth?!? So my iui will most likely be Friday or Saturday morning cuz my ultrasound is tomorrow morning. Soooo is this normal!!? Will I miss my window if my iui is done on Friday or Saturday!!? Confused! Can someone please shed some light?!?
