Ovulation Calculator
To increase your chances of getting pregnant, our ovulation calculator will help you forecast your fertility in a simple calendar format. Simply tell us the first day of your last period, and how long your cycle usually lasts (between 20 to 45 days).
NOTE: If your menstrual cycles are irregular, you may have trouble pinpointing your ovulation day based on this calendar alone, and may need to use an ovulation predictor kit.
