I had my 12 week, 2D scan a few months ago, and they gave me my date (28th April), and at 18 weeks, I had a private 4D scan, which said the baby was measuring 6 days bigger than the hospital said (which would make his due date 22nd April), but she wasnt going to change my dates.
My bump measurement has been spot on average until last week (37 weeks) where he was just slightly bigger than average.
Which date was more likely to be accurate? The 4D scan or the 2D one?
