I've heard the story that a higher heart rate is usually a girl, and a lower one is usually a boy. My mom says it was usually true for her pregnancies. My girls both had heart rates around 150ish in earlier pregnancy, which became somewhat lower (130-140) towards the end. This baby has a heart rate of 130-135, so far, and so I'm wondering if it is a boy. (I also did not throw up with this pregnancy, and have more zits and put on more weight, so far .) The Chinese Gender Calendar says it's a boy too. So it must be.
Anyone else have a pretty good idea of what they were having from the heart rate?
