Just wait and check it again mine was like that and kept getting darker and darker
but I see a fant line but take it early morning
should take another one but don't drink anything
I see it but it could be evap, I'm not really sure. I never got one before. Maybe try a dollar tree test? It's pink dye and really easy to see. Even if it's super faint :)
well you can't even see it so this was a waste of time. lol. it just really faint & idk if it's evap or not.
I just don't know if it is an evap. I hope not
