Kind of a strange question... I've been having a little bit of "am I pregnant paranoia," so I went out and bought a pack of 2 FRERs. I took the first one on Sunday, and it was negative. I was planning to take the other one in a couple more days if AF doesn't show up, but I left the other test in my car. It's been hovering around 0 degrees here for the last two days with the test in the car. Do you think it's still good? I wasn't sure how that would affect the dye. Thanks!
