Trigger + IUI first cycle!

Kay • TTC #1

Hey, ladies! I just got my follicle scan. 20-21mm and two of them! I was told to take a trigger shot on Saturday late evening if I don’t have a positive OPK that morning. The clinic is closed on Sunday, so the <a href="">IUI</a> would be scheduled on Monday. I’ve read that Ovidrel will trigger ovulation within 36 hours. Would this mean that I might miss the window? Any success stories on triggering 36 hours before <a href="">IUI</a>?
