Baking soda and urine test to predict baby's gender

Natalie
So I'm currently 14 weeks and I can't wait to find out what the sex is. So I saw that if you take 2 tbsp of baking soda and some of your urine in a glass and if it fizzs then it's a boy if nothing happens then it's a girl. Well my result was I saw bubbles rising and little fizz. So I'm not sure if that would substantiate a boy. Anyone ever try this and have the same result?
