Work out when you’re most fertile and when is the best time to get pregnant, to increase your chances of getting pregnant with our easy-to-use ovulation calculator.
All you need to do to use our ovulation calendar is put in the first day of your last period.
Then we need to know the average length of your menstrual cycle so we can calculate the window of time when you’re most fertile. While the average cycle lasts 28 days, anything from 22 to 36 days is perfectly normal, so pop your number in and press calculate.
