Hi everyone! I am 11 days post IUI, testing out my trigger shot. I am 12 days post trigger shot. I never saw it fully go away, but I think it's getting darker? I would love more opinions!

First pic is days 1-12 Second pic is 10DPT Third is 11DPT And fourth is 12DPT

These are all FMU and within 5-10 minutes of taking the tests :)
