Ovidrel - Testing Out Trigger

I'm on natural, monitored cycle (transvag ultrasounds) to make sure I actually grew follicles (we found out I do, but my pos opk was a week before I actually had a mature follicle! So, opk don't really help me!). They triggered on cd20 with a 22mm follicle to make sure I got my surge to ovulate. Anytime I have Ovidrel (twice before on Clomid cycles), I test out my trigger. Do y'all do this? When do you typically completely test out? It feels obsessive but also gives me something to do during this 2ww!
