Question about size of baby!

ndebello

Anyone have similar experiences with the following?

 At my 20 week AS my LO was measuring 2 weeks ahead. I didnt think much of it, since babies can fluctuate in growth. However, at 29 weeks at our elective 3D ultrasound at our OB he was still measuring 2 weeks ahead and estimated to weigh 3 lb 12 oz. Which I know the weight is not always accurate. Now today the ob tells me my uterus also measures two weeks ahead. Is this normal? Or is it possible my due date was off? My baby shower is being held at 35 weeks, which makes me a little nervous if I am really going to be 37 weeks. Shower is 4 hours from home.
