Take a pink dye test, blue dyes are notorious for showing the evap line way before it should show.

There’s no color to the line (at least to me) that tells me this is either and indentation line or an evap. How old is the test? Also rule of thumb if you have to tweak any picture to “show the line” there’s a good chance it’s not a positive. If you’re period isn’t due yet wait until your period is due and take a pink dye test (you can get cheap affordable ones at Walmart for .88 cents).
