Would my lines be this dark from the trigger shot still left over?

S.A.M • Mommy to twin girls!!! 🎀🎀

Had trigger shot on 12/16 so exactly two weeks ago. So I’m 14 days past trigger. I can’t convince myself fully that this is my bfp!?!? Help!! The lines didn’t get much darker or lighter on the FRER, stayed about the same but will test again tomorrow. I wanted to surprise Hubby tomorrow for New Years eve before we go out on our date. Safe to tell him we’re pregnant?!
