What is a Pregnancy Calculator?
A Pregnancy Calculator is a simple yet powerful tool that helps expectant mothers determine their estimated delivery date (EDD). It uses your last menstrual period (LMP) and cycle details to calculate how far along you are in your pregnancy.
At The Birthwave, our calculator is designed to give accurate, quick, and easy-to-understand results to support your pregnancy journey.
How Does the Pregnancy Calculator Work?
The calculation is based on a standard medical formula:
- Pregnancy typically lasts 280 days (40 weeks) from the first day of your last period
- The calculator adds this duration to your LMP
- Adjustments are made based on your cycle length
This helps determine:
✔ Estimated Due Date (EDD)
✔ Current Pregnancy Week
✔ Trimester Stage
✔ Key Milestones
