What is a Pregnancy Calculator?

A Pregnancy Calculator is a tool designed to estimate important milestones during pregnancy, such as the due date and weekly progress. It uses information like the first day of your last menstrual period (LMP) and, in some cases, the date of conception to calculate various pregnancy-related dates.

How Does a Pregnancy Calculator Work?

The most common method used by a Pregnancy Calculator is based on Naegele's Rule, which adds 280 days (or 40 weeks) to the first day of the last menstrual period. This method assumes a 28-day menstrual cycle.
