Understanding your menstrual cycle is crucial for family planning, fertility awareness, and overall reproductive health. The Ovulation & Pregnancy Calculator is a powerful, user-friendly tool designed to help individuals estimate ovulation days, identify their fertile window, and predict their next period with precision. By using this calculator, users can make informed decisions about conception or contraception.

Unlike generic calendar methods, this tool provides tailored results based on your menstrual cycle length and the first day of your last period, giving you a highly personalized insight into your reproductive health.

How the Ovulation & Pregnancy Calculator Works

The tool uses a simple calculation based on the average ovulation cycle. Typically, ovulation occurs about 14 days before the start of the next period. By entering your cycle length and last menstrual period, the calculator determines:

  • Estimated ovulation day
  • Fertile window start and end
  • Expected next period

This information can be used for conception planning, fertility tracking, or simply understanding your cycle better.

Practical Example

Suppose your menstrual cycle is 28 days, and your last period started on November 1, 2025.

  • Estimated ovulation day: November 15, 2025
  • Fertile window: November 10–16, 2025
  • Expected next period: November 29, 2025

This means that the most fertile days for conception are between November 10 and November 16, with ovulation occurring around November 15.
