The Doc says I have a big baby

I had my 25 week OB appointment today. They measured my belly with a tape measure. They didn't do this step at my last appointment 4 weeks ago, but the one before that I was measuring right where I was supposed to. This time the doctor measured me, went to my chart, came back, and measured me again. Sure enough, I'm measuring like I should be around 28 weeks instead of 25 weeks. I've only gained about 10 pounds which is normal if not low, so it's all baby. He's going to do an ultrasound at my next appointment in 4 weeks. I remember with Paige I had extra amniotic fluid in there so I was bigger than usual with her too. Paige was also born 2 weeks early, so I'm thinking this one may be an early bird as well.
