Estimated weights

stephanie
So I carry small and measuring small. I had a growth scan done at 31 weeks and she weighed 3lb 8oz. I had another today at 36 weeks 1 day she's only gained 1000g (2lbs) but they estimated her weighing 6lb 2oz... which obviously adding 2lbs on to 3lb 8... doesn't make 6lb 2... what do you all think... and what did yours all come back at 36 weeks
