Can someone please explain the bleach pregnancy test to me!?!

Okay so I’ve done my research but I want to think I did it wrong because I think I may have added too much bleach okay so I peed in a cup and then I poured bleach the pee was still warm not sure if that could of affected it too.okay so my pee was fizzing a little I added more bleach and it frothed so much it spilled everywhere helppppp I’m freaking out!?!! Did I do this wrong!?!! Is that a false positive?!
