Okay ladies!
Has anyone tried this baking soda gender test?  
I'm only 8 weeks Friday so I am assuming it is maybe too early, but I added the one table spoon of baking soda to my urine and it was flat, no fizzing.  This apparently means girl.  If it fizzes like a draft beer, it's a boy!
Anyone try this with success?!??
