Pregnancy Calculator
This version of the pregnancy calculator can be used for what-if planning. For example, you can use it to find out approximately when your baby would be due if you conceived on {fill in the date below}. If you know approximately when you're fertile during your next several cycles (tip: Use our ovulation calculator!), you can use those dates to see when your baby would be due if you were to conceive.
Due Date Based on Future Conception Date
See your Estimated Due Date if you were to conceive on a specific date.
Remember, the due date is only an estimate of when your baby would be due if you conceived on the date you specify. Only about 1 in 20 births occur on the predicted due date (that's just 5%), so for most women (95%), there will be a margin of error of a few weeks on either side of the due date.
