Ovulation Calculator
How Does the Ovulation Calculator Work?
Our Ovulation Calculator helps you predict your most fertile days and estimated ovulation date based on your menstrual cycle. By entering the first day of your last period, your average cycle length, and luteal phase length, you'll get a personalized fertility window to optimize your chances of conception.
Ovulation typically occurs about 14 days before your next period. The fertile window is the span of days when you're most likely to conceive, usually 5 days before and 1 day after ovulation.
