Our Pregnancy Calculator & Ovulation Estimator is designed to help you estimate this crucial date. Knowing your conception date can help estimate your due date and track fetal growth.

Several methods can help you pinpoint when conception likely occurred:
- Last Menstrual Period (LMP): If you have a regular menstrual cycle, conception usually happens around 11 to 21 days after the first day of your last period.
- Due Date: If you know your estimated due date, you can work backward to estimate your conception date. Pregnancy typically lasts about 40 weeks (280 days) from the first day of your LMP.
- Ultrasound: An ultrasound, especially in early pregnancy, can provide a more accurate estimate of gestational age and, therefore, the conception date.
Keep in mind that these are estimates. Sperm can survive in the female reproductive tract for up to five days, so the actual day of conception might differ from the day you had intercourse.

Our tool offers a comprehensive approach to estimating your conception date and managing your reproductive health:
- Pregnancy Calculator: Determine your due date, track your trimester, and monitor key milestones using your LMP, conception date, or known due date.

Our user-friendly interface works seamlessly across all devices, providing personalized timelines and predictions to navigate your pregnancy or plan for conception. Understanding your LMP is crucial for this calculation.
Factors Affecting Conception
Several factors can influence conception:
- Cycle Regularity: Regular cycles make it easier to predict ovulation and the fertile window.
- Sperm Health: Healthy sperm are more likely to fertilize an egg.
- Timing of Intercourse: Having intercourse during your fertile window significantly increases the chances of conception. Consider using our fertility tracker apps to understand your most fertile days.
If you're trying to conceive, understanding these factors can help optimize your chances of success.
Fertilization vs. Conception
While often used interchangeably, fertilization and conception have distinct meanings. Fertilization is the fusion of sperm and egg, while conception includes fertilization and implantation of the fertilized egg in the uterine wall. Federal policy and medical professionals consider a woman pregnant only after implantation.
