How Does the Pregnancy Calculator Work?

Our Pregnancy Calculator is simple and easy to use.

By using this calculator, you can accurately track your pregnancy progress and better prepare for the exciting days ahead.

The Pregnancy Calculator Formula

The Pregnancy Calculator uses the standard 280-day pregnancy term calculation:

Pregnancy Weeks = Conception Date + 40 Weeks
(based on the first day of your last menstrual period)

For more accuracy, consider other factors like your cycle length and the timing of ovulation, which can impact the due date slightly. For detailed medical guidelines on gestation, you can refer to Wikipedia’s Pregnancy Overview.
