Conception Calculator
Calculate your most fertile days and optimal time for conception based on your menstrual cycle.
Understanding Your Fertility Window
The Fertile Window
Your fertile window is typically 6 days long - the 5 days before ovulation and the day of ovulation itself. This is when conception is possible.
Peak Fertility
The two days before ovulation and the day of ovulation are your most fertile days, with the highest chance of conception.
Tracking Tips
Use ovulation tests, track basal body temperature, and monitor cervical mucus changes to better predict your fertile window.
Important Note
This calculator provides estimates based on averages. Every woman's cycle is unique, and actual fertile days may vary.
