Help - Ovidrel Question

Hi! We’re going into our 3rd IUI, and my doctor changed our plan this time. Took Clomid days 3-7 (was letrazole for prior cycles), prescribed ovidrel trigger, and progesterone suppositories. It’s CD9, and we have our first ultrasound / bloodwork tomorrow. My issue is don’t have the Ovidrel in yet. (!!!! Despite pulling my hair out trying to make it happen)

What days of the cycle did you guys trigger in regards to your ovulation? I normally ovulate on cycle day 15 or 16. I don’t know if I should be like driving several hours to go to a pharmacy to pick it up, or wait for it to get delivered on Monday. Need advice!
