I had my 4D ultrasound and sugar test this past Friday and after my 4D the tech told me how much she weighed and acted concerned. I was 28 weeks and 5 days. At that point a baby should weigh around 2.5 lbs.. well my baby girl weighs 3.5 lbs already. The tech said she thought I was gonna fail my sugar test, but I didn't, so I don't have gestational diabetes (thank god!!)... but my question is, is this really something that I should be concerned about? Has anyone ever has this happen to them?
