Nub theory?

Ashley
Ok ladies. This is my third pregnancy and I didn't know anything about the nub theory until this time around. Basically the nub theory says that if it's a boy the nub will point upward at a 30 degree angle or less and if it's a girl the nub will lie more flat at an angle less than 30 degrees. I am 12 weeks and 3 days today and had an ultrasound 3 days ago. I asked the technician about the nub theory and she said it is true, and based on the angle of my baby's dangle we both think it's a boy! Anyone else know anything about the nub theory or have sucess in guessing the gender based on it? Here is the picture of my baby's scan on Thursday
