Ultrasound Today

So I had my 37 week Dr. Appt yesterday. Out of all the Dr's I like Dr Fuoss best. I hope he is the one at the hospital when I go have Audrey. They gave me my "what to do in case of labor" info sheet. And he was surprised when he measured me. I am measuring 5 weeks ahead! I was measuring 2 weeks ahead and they don't worry until you start measuring 4 or more weeks ahead. I have to go get an ultrasound today to find out if she is big, if I have too much fluid, or if she was just laying in a weird position yesterday. My appt is at 1130 I will update after!
