What do u guys think?

This was a test that was negative, as soon as it was negative maybe two minutes later I tossed it in the trash. A day later I glanced down at the trash but then thought I saw a line! I look at it and the line is not pink.. At least it looks colorless. I'm not sure if it's an Evap line or if it's because it's a day old or what. I was 8dpo with this one. I took another one today but that one also was negative so I'm curious to see what it says in the morning. Glancing at the picture I don't see a positive test, when I turn the brightness of the phone up, it's there. I just can't decide whether or not it's just an Evap line or actually positive. Anyone ever had a negative test turn positive overnight and actually be pregnant?
