The average pregnancy lasts approximately 280 days — 40 weeks — counting from the first day of the last menstrual period. Your due date — what midwives or doctors once referred to as the EDC, estimated date of confinement (in the old days, women were actually ‘confined’ to the hospital around the time the baby was due) — can be calculated by starting with the date on which the first day of your last menstrual period (LMP) occurred.
