Until I was fourteen years old and in grade nine, I believed home pregnancy tests worked the same way as oral thermometers (you put it under your tongue and wait a few minutes, and then it tells you if you're pregnant or not). Imagine my shock when I was hanging out in the music room one day, and I found out the truth by overhearing some of my older friends talking about home pregnancy tests, lol.
