Ovulation pain during IUI #4

I went in on 12/30 for cd10 ultrasound and found out I have 25mm and 17mm on left ovary and 20mm on right. Just to give the 17 a chance to catch up, I was instructed to trigger 10,000ui of Pregnyl on 12/31 @ 4:30pm. Today at my <a href="https://glowing.com/glow-fertility-program">IUI</a> scheduled for 8:30am, I experience the cramps I normally get after trigger shot the night before <a href="https://glowing.com/glow-fertility-program">IUI</a>. Is it possible I ovulated more than 36 hours after shot? Did I ovulate during <a href="https://glowing.com/glow-fertility-program">IUI</a>? Has anyone had both at the same time and gotten pregnant?
