Conception Calculator
About Conception Calculation
This calculator estimates your conception date using two methods:
- Last Menstrual Period (LMP): Calculates conception date by adding 14 days to the first day of your last period.
- Due Date: Calculates conception date by subtracting 266 days (38 weeks) from your expected due date.
Important Notes:
- This calculator provides an estimate and should not replace professional medical advice.
- Conception typically occurs 11-21 days after the first day of your last period.
- The fertility window is the 6-day period ending on the day of ovulation.
- Actual conception dates may vary based on individual factors and cycle length.
