Ovulation Calendar. An ovulation calendar can help you to determine when you are most fertile and most likely to get pregnant. Calendars. The two calendars linked below will help you track your ovulation so you can estimate when you are most fertile. For women who have a 28-32 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 since every woman's cycle is different.
First of all, you need to start by figuring out how long your average menstrual cycle is. You count day one as the first day of your period and your cycle goes until you start your period again. Keep track of the days, and once you start your period again, the day before that is the last day of your ovulation cycle. Most women have a cycle of between 28 and 30 days. By counting your cycle for several months, you will be able to really start to see a pattern and figure out when you are ovulating each month. Mark your calendar. Now that you know the length of your cycle, start marking it on the calendar each month.
