Estimate Your Due Date Now →How to Estimate Your Due Date Using Ovulation
Here's how you can estimate your due date based on ovulation:
- Identify Your Ovulation Date: Track your menstrual cycle to pinpoint when ovulation occurred. Consider using our Ovulation Estimator for accurate predictions.
- Add 266 Days: Since a typical pregnancy lasts about 38 weeks from conception, add 266 days to your ovulation date.
Remember that this is just an estimate. Individual variations exist, and an ultrasound can provide a more precise due date.
Factors Affecting Due Date Accuracy
Several factors can influence the accuracy of a due date by ovulation calculation:
- Irregular Cycles: Irregular periods make it harder to pinpoint ovulation.
- Fertilization Timing: Sperm can survive for several days, so the exact fertilization day may not be the same as the day of intercourse.
- Early Ultrasound: Confirm your dates with an early ultrasound for the most precise estimate.
