HELP ME PLEASE.

I always here a lot of bad things about blue dye tests: false positives, evap lines, etc., so I swore I wouldn't bother with them.

Today I'm 9 dpo. I got off work at 1:30am and got a wild hair to go to a 24 hour drug store and get a test. I knew it was probably a waste of money but all they had were blue dye tests and I got one anyway.

So, here's my question: is this the dreaded evap line? It looks like there might be something; it's just SUPER faint...It was much darker this morning, but I know that looking at a test too long after makes it completely inaccurate. Should I go grab a pink dye test?! What's going on?!
