A member asked:

If labor/delivery occurs after your due date, did conception occur later than suspected from the dating ultrasound?

Some variability: Us dating between 8-13 weeks is the most accurate to within +/- 3-4 days. It is possible the dating by last menses may be incorrect as well, especially if menses are variable. Although most women deliver around 40 weeks, not every delivery happens at 40 weeks. Some are a couple of weeks early, others late. Please discuss any questions with your doctor.
