evap line?

Jessica

this came up hours after I tested. I'm guessing this is an evap line...but I've never had one happen before. I've read that they're gray and skinny but this one is blue and the same thickness as the control line.

I'm 3 days late and I'm NEVER late. the last time was when I was pregnant with my son. I tested the day after my missed period and got a clear positive. but now, I have no idea what's going on.
