Trigger shot ready

Cl

I just left the clinic , and have to come back at 5 pm for trigger shot and my <a href="https://glowing.com/glow-fertility-program">IUI</a> is scheduled for Friday morning , my dominant follicle was at 20, why is he waiting so long for <a href="https://glowing.com/glow-fertility-program">IUI</a>? I thought I would get it morning after trigger , how long after trigger was your <a href="https://glowing.com/glow-fertility-program">IUI</a> scheduled?
