Your due date is only as good as when the ultrasound was done. You had one done at a stage of pregnancy where there is a week's possible margin for error when trying to use ultrasound information to say a conception date. You should plan to get a DNA test when the baby is born just to be sure.
Hi, well, many doctors will say that a 12th-week ultrasound has a margin for error of +/- 7 days. A July 8 due date favors the first guy, but with a margin for error of a week, it also doesn't rule out the second guy. Is the baby a girl or boy?
Did you get your due date from an early ultrasound? If so, how early?
