The online Ovulation Calendar is used to create your personal ovulation calendar.
The ovulation calendar calculates your fertility based on your menstrual cycle information. Enter your menstrual cycle information, including the first day of your last menstrual period, your menstrual period length and your luteal phase length. Then click on "Create Ovulation Calendar" to view your personal ovulation calendar. If you don't know the length of your menstrual period or your luteal phase, you may use the default values, which represent the average woman.
After creating your ovulation calendar, you are recommended to bookmark your calendar for future reference, and you will never forget the start date of your last menstrual period.
The ovulation calendar may help you get pregnant, avoid an unwanted pregnancy, or conceive a boy or girl. For example, if you want to avoid an unwanted pregnancy, the calendar will indicate which days to abstain.
Please note that the ovulation calendar works best for women with a regular menstrual cycle.
