Each month you have a small fertile window, usually 10 to 18 days after the first day of your period. The Ovulation Calculator helps you quickly determine your most fertile days based on the date you provide and your cycle length:
- Enter the first day of your last menstrual period
- Enter the length of your menstrual cycle
The Ovulation Calculator instantly determines your 6 most fertile days in the current month and in each of the following 4 to 5 months, giving you a better understanding of your monthly cycle. The results also include the baby’s due date should you happen to conceive during that month.
Whether you’ve been trying to get pregnant for a while or are just starting to think about having a baby, the Ovulation Calculator is a great first step towards your ultimate goal — a baby to love!
