Pregnancy Due Date & Progress Calculator

Expecting a new addition to the family? Our Pregnancy Due Date Calculator helps you estimate your baby's arrival date based on the first day of your last menstrual period (LMP).

Using the standard Naegele's rule, we calculate a 280-day (40-week) pregnancy cycle. This tool also provides your approximate conception date, your current week of pregnancy, and which trimester you are in.

Note: This tool provides an estimate only. Always consult with a healthcare professional for clinical advice.
