Evap line or faint positive

[Ch07]

I took this test today 1 day before af is due. I didn’t check it straight away I put it in my pocket and checked after 10 minutes and this is what it looked like. Is this likely to be an evaporation line?

I'd retest and try to look at it straight away of that makes sense. There's a lot of dye bleed across the whole test which would make me think this one is invalid. Good luck!
