Find Your Estimated Due Date: See How Far Along You Are

If you think you might be pregnant or recently found out that you are, our Pregnancy Calculator can help you estimate how far along you may be.
Simply enter the first day of your last menstrual period (LMP) to get an idea of your possible due date and key pregnancy milestones.

This tool is a helpful starting point — but remember, every woman’s body is unique. For the most accurate confirmation, we recommend scheduling a free pregnancy test and consultation at Loreto House.
