When can I test?!

Cait • TTC since August 2015. 4 IUIs. 1 👼🏻. IVF stims to begin in October with retrieval in early November.
12dpt and 10dpiui. I want to test so badly!!!! This is taking so much self control! This is my first <a href="https://glowing.com/glow-fertility-program">IUI</a> and I'm used to testing like 4 days before AF. When do most of you have the trigger shot tested out? I know it depends on the dosage, just looking for some averages!
