Ovidrel

Tonight I triggered with Ovidrel 250mcg/0.5ml injection. How soon after trigger can you do a urine pregnancy test? I’ve heard that you’re supposed to test out the trigger, but what does that mean? Any advice is welcome as this is my first time using Ovidrel and I will have my first <a href="https://glowing.com/glow-fertility-program">IUI</a> next week. I have a blood pregnancy test scheduled for 2 weeks after my <a href="https://glowing.com/glow-fertility-program">IUI</a>, but I’d love to know even sooner! Thanks!
