Due dates are also calculated based on the baby's body length during an ultrasound between eight and 12 weeks of pregnancy, according to Dr. Sachchidananda Maiti, England-based obstetrician and gynecologist.
For example: If you have an ultrasound before you're 14 weeks along and the fetal size suggests a due date that's more than seven days different from an estimated due date based only on your menstrual period, the ultrasound due date should be the one that is accepted as accurate.
