When to test?

Janelle

Tomorrow I will be 12 days post IUI and 14 days post trigger shot... If that too soon to take a test? My period is due on Thursday. I'm trying my hardest to make time go faster and to not take a test but I really want to! Do you think that its safe to say trigger will be out of my system? I really wouldn't want to get a false positive and get my hopes up.
