Ovulation Calendar

BabyHopes free ovulation calendar will help you calculate your most fertile days for getting pregnant. For most women, ovulation occurs approximately 14 days before the start of your next menstrual period. Knowing when you ovulate will help you time intercourse increasing your chances of getting pregnant.

Before proceeding, there are a few things to keep in mind when using this ovulation calendar:

  • Cycle lengths of more than 35 days are too long for appropriate calculations.
  • Cycle lengths of less than 21 days are too short for appropriate calculations.
  • Our calendar cannot be used to reliably prevent pregnancy.

The length of your menstrual cycle is calculated by counting the number of days from the first day of menstruation to the day before the following menstrual period starts.

If you don't want to use a calendar to count the length of your menstrual calendar, you can enter the dates of when your period started on consecutive months and figure it out that way! Easy Peasy :D
