Homemade pregnancy test

Have anyone tried the bleach home made pregnancy test? I tried it for the fun of it cuz I haven't felt right. And didn't have a pregnancy test handy at home. So has anyone done this and actually had the frothy foam on top and actually tested and been positive? If you don't know about this test you put half bleach and half pee in a cup and if it's foamy and frothy it's positive. And if it's not then it's negative. Please let me know :) I added a picture of what it looks like also! Thanks in advance ​
