Due date moved?

Cheyenne • 👦🏼3/2015❤️👪9/2017❤️🌈9/2018❤️🤰🏼10/2019

We had an elective 3d ultrasound done last night and she said she’s measuring way ahead. Her legs were almost 3 weeks ahead and the rest of her body was two weeks ahead. If we go off of measurements she will be 33w today. I’m supposed to be only 31w. I’m going to mention it to the dr and see what she says but is there any chance she would move my due date up since it wasn’t done in office? I know babies flux in height and weight but she was estimated 4lb 8oz already. Pictures of our sweet chunky🥰❤️
