Use the Ovulation Calculator to find out when your ovulation date is, and increase the likelihood of getting pregnant. The Ovulation Calculator shows your fertile days - keep in mind that you are most fertile on your ovulation date.

On average, there are 28 days in a menstrual cycle - it can last from as little as 22 to as many as 44 days. The Ovulation Calculator gives you the approximate ovulation date, but if your cycle is irregular the results may be less accurate.
