About Your Baby This Week
Understanding Due Dates
Your due date is an estimate of when your baby will be born, calculated as 40 weeks (280 days) from the first day of your last menstrual period. Keep in mind:
Only about 5% of babies are born on their exact due date
Most babies arrive between 37-42 weeks
First-time mothers often deliver slightly later (40 weeks 5 days on average)
Your healthcare provider may adjust your due date based on ultrasound measurements
Early ultrasounds (before 13 weeks) are the most accurate for dating
