First response ⚠️FALSE POSITIVE ⚠️warning!! *update*

I just wanted to hop on and let y’all know that I took a first response test on Wednesday night and got a faint positive (faint but VERY visible). I was suppose to start period yesterday (Thursday) and didn’t. I’ve taken 3 other brands since yesterday including another first response they have all been negative. Still no period. I am thinking it’s just late. I’ve been seeing a lot of these posts about first response giving them false positives as well.

*Edit: the positive line showed up as soon as I peed on it and it was pink. Definitely not an Evap.

*UPDATE*

Just wanted to update and say I’m currently 4 days late and still no period or positive test. Idk what is going on.
