Interpreting Results
The estimated due date provided by this calculator is an average. Actual due dates can vary by several days. Here's what the different calculation methods mean:
- Last Menstrual Period (LMP): This method adds 280 days to your first day of your last menstrual period. It's a common estimation method but can be less accurate than ultrasound-based calculations.
- Ultrasound Date: This method uses your baby's gestational age at the time of the ultrasound to calculate a more precise due date.
For the most accurate due date, consult with your healthcare provider, who may use additional factors like your menstrual cycle length and ultrasound measurements.
