Calculate Conception Date →How to Estimate Intercourse Date from Due Date
Pregnancy is typically calculated as 40 weeks (280 days) from the first day of your last menstrual period (LMP). However, conception usually occurs around two weeks after the LMP, during ovulation. Therefore, to estimate the intercourse date:
- Determine your Due Date: This is usually provided by your healthcare provider.
- Subtract 40 Weeks: This will give you an approximate date of your last menstrual period (LMP).
- Add Two Weeks: This approximates the date of ovulation, and thus, when conception likely occurred.
Keep in mind that sperm can survive for up to five days in the female reproductive tract, so intercourse could have occurred in the few days *before* ovulation as well. Learn more about day of conceived.
Factors Affecting Accuracy
Several factors can influence the accuracy of this calculation:
- Irregular Cycles: Women with irregular menstrual cycles may find it more difficult to pinpoint ovulation.
- Early or Late Implantation: Implantation can occur between 6-12 days after ovulation, slightly affecting the estimated conception date.
- Incorrect Due Date: An inaccurate due date will throw off all calculations. Confirm your due date with your doctor.
For irregular periods, it is best to use a irregular period calculator.
Using Our Pregnancy Calculator & Ovulation Estimator
Our tool simplifies this process. If you know your due date, the pregnancy calculator can work backwards to estimate your conception date.

The Role of Ovulation Tracking
If you are trying to conceive, understanding your ovulation cycle is critical. Using an ovulation tracker or estimator alongside calculating intercourse date can provide a more complete picture. Also, understanding the most fertile in cycle can help with the timing of when you have intercourse.
