Gender prediction

So anyone whose talked to me about gender prediction methods knows I think they're all bullshit. All of the charts, old wives tales, and other such nonsense methods are typically only correct 50% of the time.

The Chinese Conception chart said Penelope was going to be a boy. Wrong! It was the only one I did for her since we found out her sex at 17 weeks.

This time we're holding out until the end, so I though it would be fun to do a couple of the gender prediction methods and come back after the baby is born to see how many guessed wrong.

Chinese Conception chart: Boy
Ring test: Boy
Heart rate: Girl (FYI, for this over 140 = girl, under 140 = boy)
Old Wives tales (it was a quiz): 67% chance of a girl, 33% chance of a boy

So 50/50 according to the unscientific gender prediction methods. Which is what I figured it would be.
