Very very very faint line, negative or evap line/indent?

I’ve done a pregnancy test Tuesday evening and I wasn’t sure I could see a line but I posted here and they said they could see a very faint line. So I’ve done another testing the Wednesday evening because I was inpatient to find out if was pregnant or not but it looked negative. The only thing is on Wednesday afternoon I had a really bad headache all of the sudden and I decided to drank more water because I thought I was dehydrated. So I don’t know if this could have made any difference.

So I’ll attach some pictures: the first 3 (easy at home) are from Tuesday evening and the others(Clear Blue+ easy at home) are from Wednesday evening!

Let me know your thoughts!
