due date by last menstrual period or by early ultrasound stiil accurate. with my first baby my ob wanted to move it 3 weeks earlier coz the baby was ahead 1 month by size in the ultrasound.
My due date went from 10/27/15 to 10/14/15 and I'm still measuring big however the only date that matches with my lmp is 10/27/15 my lmp was 1/20/15 - 1/25/15 and my first u/s was perfectlyatch with my lmp y conception date and the size of my baby now it's not? should I be worried or is it that my son is a bigger baby?
