help! evap line or positive?

jaderbug 🌈

so my friend sent me pics of her pregnancy tests, and faint lines like this showed up after a few tests. with a clearblue & first response. however, she got 2 negatives yesterday on a digital and another one. the faint lines showed up immediately. could it be evap lines coming up on both the clearblue and first response?

there’s the digital that says no, and then the one under is blurry i can still see a line?
