Trigger shot---when do I take HPT?

Dee
Hi everyone! I started clomid for the first time this cycle and also used a trigger shot (ovidrel). My OPK was positive a few days earlier, so I'm not really sure when my period is supposed to come (Glow is to predicting Friday). I gave myself the trigger shot two weeks ago today, and I was wondering when I should test. Part of me is wanting to wait until AF, but the other (impatient) part can't wait, as we will be doing <a href="https://glowing.com/glow-fertility-program">IUI</a> this cycle if we don't get our BFP.
Thank you in advance for your help!
