Ovulation Calendar: How To Track Ovulation

Email

Use the calendar below as a guide to help you track your ovulation. For women who have a 28 to 32 day menstrual cycle, ovulation can take place between days 11 through 21.Remember this is just an average of days that ovulation could take place--every woman's cycle is different. A woman who has a 27-28 day cycle will most likely ovulate in the earlier part of the window. Those with a longer cycle will often ovulate later in the fertility window. To get an accurate day of ovulation for you, it is encouraged that you use one of the many methods discussed in fertility awareness, or by using an ovulation predictor kit.

Mark the date that corresponds to each day of your cycle, starting with the first day of your last period. Be sure to read about Fertility Awareness/Natural Family Planning before using an ovulation calendar to help prevent pregnancy.

Ovulation Calculator

Another way to track your ovulation is to use an ovulation calculator, which uses the same principle as the ovulation calendar.
