Pregnancy Conception Calculator

Calculate your estimated due date (EDD) using last menstrual period, conception date, or ultrasound measurements.

Pregnancy Due Date Calculator

Calculate your estimated due date (EDD) using different methods recommended by healthcare professionals.

Calculate your due date by adding 280 days (40 weeks) to the first day of your last menstrual period using Naegele's rule.

Most accurate when used early in pregnancy for women with regular 28-day cycles. Accuracy may vary if your cycles are irregular.

Best for: Early pregnancy (before 12 weeks) and regular menstrual cycles

Cycle Length

Pregnancy Conception Calculator: Professional Tool for Pregnancy Dating and Due Date Calculation

Our advanced Pregnancy Conception Calculator serves as a comprehensive pregnancy dating tool for determining conception dates, calculating due dates, and tracking pregnancy milestones. This pregnancy conception dating calculator integrates medical expertise with precise algorithms to deliver accurate pregnancy calculations based on established obstetric standards.

Understanding Your Pregnancy Conception Calculator

The Pregnancy Conception Calculator offers multiple calculation methods to help healthcare providers and expectant mothers accurately determine conception timing and track pregnancy progression. This advanced pregnancy conception dating tool provides precise calculations for conception timing, gestational age assessment, and estimated due date (EDD) determination. Our Pregnancy Conception Calculator's multi-method approach ensures optimal accuracy for proper prenatal care planning and fetal development monitoring.

Core Pregnancy Conception Dating Methods

The Pregnancy Conception Calculator employs three primary calculation methods for accurate pregnancy dating:

  • Gestational Age Assessment: Our pregnancy calculator determines gestational age using LMP data, providing a foundation for conception dating calculations.
  • Conception Date Determination: The pregnancy conception calculator precisely estimates when conception occurred, enabling accurate pregnancy timeline tracking.

Pregnancy Conception Calculator Timeline Results:

  • • Early Pregnancy Dating: Weeks 1-12 (LMP-based conception calculation)
  • • Mid-Pregnancy Dating: Weeks 13-26 (ultrasound-verified conception dating)
  • • Late Pregnancy Dating: Weeks 27-40 (confirmed due date tracking)
