I know the results are invalid...

First of all, I'm not trying to get pregnant right now. I have a 9 month old, and I'm just not ready for baby number two. Long story short, I've been feeling extra--I mean extra--emotional lately, so I decided to take a test. It was negative. Like stark white negative. A  couple hours later, my DH went into the restroom and saw this (see picture). I know it's invalid after 5 mins or so, but has anyone seen something like this before? I've never seen a pee test show a line, with color, after the time limit.
