I took a test Wednesday night and i didn't wait a full 2 mins b4 reading the results. I just looked right when I was done and it was negative so I stuffed it back in the box and left for church. For some reason when I got back from church, I checked it again as I was throwing it away. There was a faint positive. I have always heard evap lines are silverish but this line is very bright bkue, it's just thin. Any thoughts??
