Ovulation Calculator

Calculating your ovulation cycle can help predict the days when you are most fertile, and as such can improve your chances of getting pregnant. Use our ovulation calculator to find out when your fertility is at its natural peak.

This method works by calculating the first day of your last menstrual period along with the typical length of your menstrual cycle. Every woman’s cycle is different, and a general prediction of ovulation may not work in every case. An ovulation calculator can never replace medical advice, but it can provide you with a general sense of when you are most likely to conceive.
