Uterus measuring big .

Anita
Just went for 16 week checkup, Dr measured my uterus, which I read was suppose to be below you belly button at this point, mine is above my belly button! So, of course I googled and that is where it's suppose to be around 22 weeks. Anyone else having this issue? Dr didn't seem concerned, just got an "Oh wow you're already up here " lol .
