Trigger and timing

Kc • 27-married-Ohio
My RE office only does <a href="https://glowing.com/glow-fertility-program">iui</a>'s until noon everyday...we are doing a trigger shot this month before it. When do you think my trigger shot would be if my <a href="https://glowing.com/glow-fertility-program">iui</a> was supposed to be at about 9am?
