Estimate Your Due Date Now →Understanding the Ovulation Method
The average pregnancy lasts about 40 weeks from the first day of your last menstrual period (LMP). However, this method assumes a regular 28-day cycle with ovulation occurring around day 14. If your cycle is shorter or longer, or if you know your ovulation date, calculating from ovulation can be more accurate.
How to Calculate Your Due Date from Ovulation
- Identify Your Ovulation Date: This is the key. Use ovulation predictor kits (OPKs), basal body temperature (BBT) charting, or cervical mucus tracking to pinpoint the day you ovulated.
- Add 266 Days: Once you know your ovulation date, add 266 days. This is the average length of pregnancy from ovulation to birth.
For example, if you ovulated on January 1st, adding 266 days would give you a due date of September 24th.
Factors Affecting Due Date Accuracy
- Irregular Cycles: Women with irregular cycles may find the LMP method less accurate.
- Ovulation Tracking Accuracy: The more accurately you track ovulation, the more reliable your due date calculation will be.
- Early Ultrasounds: An early ultrasound (ideally before 13 weeks) is the gold standard for confirming gestational age and adjusting your due date if necessary.

When to Consult a Healthcare Provider
While online calculators can be helpful, it's crucial to consult with a healthcare provider to confirm your due date and ensure a healthy pregnancy. An early ultrasound is often recommended to verify the accuracy of your due date and assess the baby's development.
