“The average length of pregnancy is 280 days, or 40 weeks from the first day of a woman’s last menstrual period.
Your due date is used as a guide for checking your pregnancy’s progress and the baby’s growth and age. Doctors often use more than one method to check the age of the fetus and set the due date. The size of the uterus may help assess the age of the fetus. Ultrasound also may be used to help confirm the age of a fetus.”
