Been sick all day and I have a major problem... I got a pregnancy test box at Walmart and it had two in the box. I open both to see what it looks like and saw the control window was already marked with a blue line. the box showed blank and it smelled like pee. but I just got it out of the package. I had just opened it. so why did it smell like pee?
