12 DPT, 10 DPO - Help!!

Hi all,

I’m going through IUI and am 12 DPT, 10 DPO. I KNOW I’m not supposed to be testing yet, BUT I had my daughter through IUI and had a true positive with her 10 DPT, 8 DPO, so I feel like I sort of know my body’s parameters for testing out the trigger. I am testing positive today with all my tests (FRER, Mommed, Bird and Be, Wondfo), and not squinters— pretty decently visible lines. The reason I’m freaked out is yesterday (11 DPT/9 DPO) I had a positive digital (clear blue and Walmart brand). Today my digital is negative. Is it possible that yesterdays was both my natural HCG and the trigger, and now the trigger is out of my system? Or is this a really bad sign?

This morning’s test
