Gender speculations

In lieu of finding out what the sex is during the 20 week ultrasound, I'll post my speculations to pass the time until birth. So here's what I've come up with:

My intuition
Obvious
Boy

DH's intuition
Obvious
Girl

Baking soda test
Baking soda mixed with urine. If it fizzes, it's a boy, if it doesn't, girl. Done at 8 weeks
Girl

Chinese gender predictor
An ancient chart taking the mother's age and month of conception
Girl

The Bump's Chinese gender predictor
Same as above
Boy (I do not know why theirs is different than every other one I've seen, since they should all be working off the same chart)

Looks
Clear skin equals boy, breakouts mean girl
Girl

Bump position
Carrying high means girl, carrying low means boy
Boy

Heartbeat rate
Heartbeat 140 BPM or less means boy, and a heartbeat greater than 140 BPM means girl
Girl

Total tally
Girl: 5
Boy: 5

I must also note though, that everyone who knows me IRL thinks I'm having a girl. They don't say how they know, other than just a gut feeling.
