Faint line! SOS

Amy

I have taken 4 tests, two neg and two with faint lines! I changed the filter to try and show the line clearer but I’m just not sure, some are saying they see nothing at all others that they can see a really faint line. At the bottom is a pic of the test next day, all the others still show negative so not sure if evap line or if it’s showing clearer now

Test next day

What do you guys think?? Opinions greatly appreciated x
