So confused

Emily

So I started out the day taking this test around 8am. I could kind of see a line or so i thought so when I came home for lunch I took another test.

this is the 2nd test around noon which kind of shocked me. I couldn’t believe it got that much darker in 4 hours.

I went out and bought a FRER to try to confirm and this is what I’m stuck with now

I think I can just barely see a line but this whole thing is driving me crazy so I can’t be too sure. I would’ve thought that if I got a darker line on a cheap test it would really show on a FRER. What do you all make of this? 😰 please helppppp
