Example of Using the Calculator

Let’s see an example:

  • Last Menstrual Period: January 1, 2026
  • Average Cycle Length: 28 days

Step 1: Calculate Days Since Last Period

  • Suppose today is February 10, 2026.
  • Days since January 1 = 40 days

Step 2: Determine Weeks Pregnant

  • Weeks pregnant = 40 ÷ 7 ≈ 5 weeks

Step 3: Estimate Conception Date

  • Conception typically occurs about 14 days after the first day of the last period.
  • Estimated conception date = January 15, 2026

Using the calculator, you can instantly see that you are approximately 5 weeks pregnant, 40 days have passed since your last period, and the likely conception date was January 15, 2026.
