I need eyes I think I'm going crazy

Ok guys I need help I know you aren't supposed to look at a test after the time frame but I could have sworn I saw a faint line when I took it super early this morning like 430 and I took it on my way home i took a picture and then I looked again just a while ago and I can see it. Do evaporation lines get darker or could it have been a vvf 1st that it darker.

1st pic is like 3 minutes after taking it.

2nd pic is the one I just took (I did take it out of the casing to get a better look) *help can someone tweak them?*
