Reading the calendar

After you complete the steps described above, Ovulation Calendar calculates the unsafe days:

Fertility Chart

The unsafe days are marked with 'stop signs'. To avoid an unwanted pregnancy, abstain from unprotected sexual intercourse during these unsafe days. The most fertile day is the day of ovulation. The day of ovulation is marked with a light-green circle on a dark-green background. See Ovulation and Contraception for more details.

Staying informed of the unsafe days

Ovulation Calendar can alert you about the unsafe days by showing pop-up reminders when your computer starts up. To turn these reminders on, click the Configure button located in the bottom part of the main window. See Configuring Ovulation Calendar for more information.

Keeping the calendar accurate

To ensure that the calendar is correct, you need to keep your menstrual cycle information up to date. Ovulation Calendar will alert you when this information becomes outdated. To update it, click the Edit button on the left side of the main window. See Keeping the Calendar Accurate for more details.
