Anoother question I checked and see there is a limit for 3D scan as 34 week. At my last scan my baby was 1 week bigger I dont know how is he now but, I want to go at 34 week. What is my baby is bigger again and if he is 35 weeks? Will it be a problem? At 3D can also learn the weight, lenght? And I wonder if the baby is bigger one week does it mean will the baby will born approximately one week earlier?
