How soon did you test after hcg trigger?

Hazie
I know that it's very possible for false positives. So I'm not going to test early. But, were doing the hcg trigger with <a href="https://glowing.com/glow-fertility-program">iui</a> this month. Is 12 days too soon to test, or should I wait till 14?
​I might just start at 12 and see if the line gets darker. Just curious if anyone else was in a similar situation. Thanks!
