Pregnancy Conception Calculator

💡 How It Works

Pregnancy typically lasts 40 weeks (280 days) from the first day of your last menstrual period (LMP). Conception usually occurs about 2 weeks after your LMP. If you know your due date, the calculator simply subtracts 38 weeks (266 days) to estimate when conception likely occurred.

👩‍⚕️ Example:

• If your due date is July 10, 2026 →
• Your estimated conception date is around October 17, 2025
• Your fertile window was likely from October 12 to October 18, 2025
• Your LMP likely began around October 3, 2025

💡 How the Conception Calculator Works

Pregnancy typically lasts 40 weeks (280 days) from the first day of your last menstrual period. Conception usually happens about two weeks after your LMP, around ovulation time. If you already know your due date, the calculator subtracts 38 weeks (266 days) to find your likely conception date — since conception generally occurs about two weeks after your LMP.

• 🩷 Date of Conception: When fertilization likely occurred
• 🌸 Fertile Window: The days when you were most likely to conceive
• 🩸 Last Menstrual Period (LMP): The estimated start date of your last period

👩‍⚕️ Why This Matters

Knowing your conception date helps you understand your baby’s gestational age, track important pregnancy milestones, plan prenatal visits and scans, and build a stronger emotional connection with your pregnancy journey.
