If you mix female urine with bleach and it foams does it mean she is pregnant?

It's a myth. I just read that same thing online and decided to try it as I am trying to conceive. It instantly foamed up. So to test the theory, I had my husband do it too to see what happened. It also foamed up and clearly he is not pregnant. Also, don't try it because it is also a chemical reaction with the amonia in your urine and we just almost killed ourselves with the fumes it emitted.
