Do I "buy" them. No not really. It's all a 50/50 chance anyways. I rely on the u/s mostly, but even then that's not 100% accurate, so birth is the only real way to know - and in my case, even then a kid may throw you for a loop later down the road! LOL
The one Chinese Gender test gives me a 50/50 shot because if I move my conception day to any of the 4 days I could have conceived it goes b, g, b, g - so . . .!?!?
I tried the baking soda one, and I guess it said girl but then the youtube videos show women who got dualing results. The first one they did was one way and the second one they did for the camera was another way. I've only done the draino test once. It's too messy and not worth it to me to try again so I refuse that one.
My instinct is a boy, but that stupid pregnancy psychic told me a girl . . . twice. But then again she was wrong on the conception, sooo?! I'm too afraid to ask my medium friends because I don't want to tell yet, LOL But I'd love other opinions.
The Magic 8 Ball said yes to both a boy and a girl too!
I'm just going to have to wait until my birthday to find out I guess!

Still crossing my fingers for a boy!
