Just got back from the doctor today, and normally the uterus should be about as many centimeters above the pubic bone as you are weeks along. So, my uterus should be measuring at about 26 cm right now. But it's already at 28 centimeters! We're just going to keep monitoring the size (now my appointments are every 2 weeks), and make sure everything is ok. The doctor asked how big we were as babies, and when we told her 9 and 10 pounds, she was assured that this was probably just going to be a big baby.
