This tool calculates your baby’s expected due date based on your last menstrual period.
How to Use the Pregnancy Due Date Calculator
To calculate your estimated due date, you’ll need to provide the following information:
- Last Menstrual Period (LMP): The date when your last menstrual cycle started.
- Average Cycle Length: The usual number of days from the start of one period to the start of the next.
- Average Luteal Phase Length: The number of days between ovulation and the start of your period.
How the Calculation Works
The calculator estimates your ovulation date based on the average cycle length and luteal phase length you provide. It then calculates your estimated due date by adding 280 days to the first day of your last menstrual period. This is based on the average pregnancy duration of 40 weeks.
Limitations
The estimated due date provided by this calculator is just an estimate and may not accurately reflect your actual due date. Many factors can affect the accuracy, including irregular menstrual cycles, variations in ovulation timing, and individual differences in pregnancy duration. It is always best to consult with a healthcare provider for an accurate assessment.
