Homemade pregnancy test..

Shelby • 21. Married to the love of my life. TTC for 3 years.
Waiting for doctor to call with blood test results tomorrow so in the mean time I wanted to try this at home DIY test. Now, I know this isn't like totally accurate. 
But I read that if you pee in a cup then put bleach in it, if it has a foaming reaction then you are pregnant.
Well I did it and immediately it start foaming up and almost foamed its way out of the cup and it was sizzling...
(I'm well aware of myths and old wives tales) but has this ever been true for anyone??
