@MissDaphne - No, you're not the only one--I had trouble with that, too. It's funny that your doc didn't measure it or anything. My sister had a home birth with her second child and I was there for it, so I also went to one of her checkups (also at home). Her home birth midwife whipped out a tape measure to check the height of the fundus.
You would think that an OB would be more into measuring and making sure everything was just so. Your OB must be a pretty laid-back guy.
