Real BFP? 14 days past trigger and 13 past IUI. Please comment!

Okay I'm FREAKING OUT. Obviously I know these lines are there; they are super dark and came up instantly. Could this still be from the trigger shot (10,000 units of Pregnyl) administered 14 days ago? Or IS THIS MY RAINBOW BABY? .... or babies 🤔 (3 follicles this month, no fertility issues, and hubby had great swimmers and lots of them as usual!)
