Ovulation Fertility Calendar
 
An ovulation fertility calendar helps predict the days you are most likely to be fertile based on patterns of your menstrual cycle.

It uses the date of your last period and the average length of your menstrual cycle to determine the most likely dates of ovulation and fertility.

If these dates are not known, you should begin keeping track to maximize the accuracy of your calendar.

Some ovulation fertility calendars can also help you predict the dates of your luteal phase and the estimated date of your next period. Ovulation fertility calendars can only provide approximate dates of ovulation and fertility.

There are many variables that can cause ovulation cycle irregularities.

Women with irregular menstrual cycles may have less accurate calendars than those with regular cycles.

To optimize your chances of pregnancy, the ovulation fertility calendar should be used with other fertility prediction methods.

Ovulation fertility calendar software is an excellent way to track your ovulation cycle within the privacy of your own home.

Although ovulation fertility calendars are useful tools for predicting the approximate dates of fertility, they should not be used as a means of birth control.
