To determine when your baby is due, a common method is to calculate 40 weeks (or 280 days) from the first day of your last menstrual period (LMP). This calculation assumes an average 28-day menstrual cycle with ovulation around the 14th day. Since exact conception dates are hard to pinpoint due to variability in ovulation and sperm viability, healthcare providers typically use LMP for estimating the due date. If more accuracy is desired, early pregnancy ultrasounds or tracking ovulation can refine the estimate. It's important to remember that the due date is an estimate, and actual birth can occur anywhere between 37 and 42 weeks of pregnancy. If the exact date of the LMP or conception is known, a due date can be calculated more precisely using appropriate tools or with the help of a healthcare professional.
If the first day of your last menstrual period or conception date is provided, a specific due date can be calculated. Would you like to provide that information to find your estimated due date?
