Do you ever think about going off the measurement of it's 2 weeks more along? As in baby may be here earlier. This is my second but my first measuring early I have to have a repeat csection so this one will be set up in advance. I'm curious if they will go off the baby's growth and size or my due date??? Oh and they are seeing me every 4 weeks for a growth ultrasound and my doc is already seeing me every 2 weeks.
