Knowing your ovulation date will give you the best chance of becoming pregnant
The Ovulation Calculator helps you predict your most fertile days of the month. As you already know, the menstrual periods vary from woman to woman and month to month.
Use the Ovulation Calculator to increase your chances of getting pregnant by helping you determine the timing of your ovulation and peak fertility.
The Ovulation Calculator will show you your most fertile dates based on your last period date and your period length.
Find out when your next period is expected to start, when you are likely to ovulate and increase your chances of getting pregnant.
Please remember that your due date is only an estimate. On average only 5% of births take place exactly on the estimated due date. Most are born within a week either side of the estimated due date.
