I saw some homemade pregnancy test and they seem to be "very accurate". I took a pharmacy one and it's negative but my period hasn't come this month (it came the last 2 months after sex) and I'm confused. So I'm trying some homemade ones that "work". There's one I just did, the toothpaste one: you add a spoon of white (all white, normal) toothpaste to a container and then a little of your urine. If it turns light blue you're pregnant, if not then you're not. Mine was white all the time.
