What is the expected due date if the last menstrual period was February 16th?

If the first day of the last menstrual period was February 16, the estimated due date is typically calculated based on a standard pregnancy duration of approximately 40 weeks (280 days). The due date can usually be estimated by adding 280 days to the first day of the last menstrual period. To simplify the calculation, the "add 9 to the month or subtract 3, add 7 to the day" rule is commonly used. In this example, adding 9 to the month of February results in November, and adding 7 to the day (the 16th) gives the 23rd. Therefore, the estimated due date for a last menstrual period starting on February 16 would be around November 23. It's important to note that the due date is only an approximate estimate, and the actual delivery date may vary within two weeks before or after this date. Pregnant women should always be prepared and follow their doctor’s recommendations regarding prenatal checkups and delivery planning.
