Positive frer to negative? Need help 😔

I posted my first response test here and everyone saw the faint line, I don't think it was an indent or whatever because it had color and showed up in the correct time frame. Super pumped!! However, I've tested again with first response, blue dye (dye ran on both of them 😒) and now strips and they're all negative 😞 I don't know how many dpo I am but I know I ovulated around feb 26-mar 4. Haven't gotten my period, haven't had signs of her either. I'm just so confused and upset, I don't know what to think. Here's my vf positive (enhanced color to see it on camera) I got Saturday morning fmu and most recent strip I took at 10:30am today.
