Home Pregnancy Test

My friend thought it would be fun to do a "pregnancy bleach test" where you pour some bleach in the cup with your pee. We did it and mine fuzzed up , not like foam but it was like fuzz off of a soda. And when we checked online it didn't say how to know which meant positive . So I was wondering if any of you did or have ever done this? I've sort of freaked myself out. I'm probably going to end up going to town and buying a test but still .
