Pregnancy Due Date Calculator Week by Week

A Pregnancy Due Date Calculator is a tool that helps expectant mothers to estimate the date their baby is expected to arrive. There are different ways to calculate a due date, but the most common method is based on the first day of the mother’s last menstrual period (LMP). To use the calculator, the mother must enter the first day of her last menstrual period and also provide information about the length of her menstrual cycle. Based on this information, the calculator will calculate an estimated due date.

It’s important to remember that your due date is only an estimate and many factors can affect it, so it’s always best to consult with a health care provider who can consider other factors to determine a more accurate due date, such as ultrasound results. , physical exams, etc.
