Recently I read about experiments to turn a pregnancy test positive with other liquids. I decided to put it to the test. After all I didn't want to get a false positive on a test and be disappointed later. Don't take my word for it, look at the pictures! Sprite and Crystal Light gave me faint lines on a pregnancy test. Although it will be diluted when we take a urine test, I'd rather keep these things out of my body to begin with. So far my readings lead me to believe it has something to do with sugar...Have you guys tested anything?
