Evaporation Line?

I've heard horror stories of false positives/evaporation lines so not excited yet. Took in the afternoon, not first urine, 3 days from AF. Honest thoughts? Feel like I'm seeing it because I want to, but I've seen "positive" tests on here just as light. Will test again in a few days...it's the circle window, verticle. It is darker than the camera makes it look.
