Baking soda and urine, who knows about this?

Iris
So I've seen this thing were woman mix urine and baking soda to determine baby gender, does anyone know what's up with that and if is real and accurate or what? Please, I'm 7W4D and desperate to know my baby's gender, honestly I'll love to have a girl because I have 2 boys. But what ever God bless me with I will love him/her the same as I love my 2 boys.
