Use the free ovulation calendar below as a guide to help you track your ovulation. Some people also refer to this as an ovulation calculator.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.What is ovulation?
When you ovulate (or release an egg from your ovary), that egg has a chance of getting fertilized. When that egg gets fertilized, youre pregnant!
Youre most fertile from two to three days before you ovulate through the day of ovulation. If you know when youll ovulate, you can time sex accordingly and boost your chances of getting pregnant (or of preventing pregnancy, if thats what youre trying to do). Here are three ways to pin down when its happening, from the simplest to the most accurate.Use the calendar method
The easiest way to estimate when youll ovulate is to count back. First, figure out what day your next period will probably start. (If your period is very irregular, this method wont work for you.)
From that day, count back 12 days and then another four. Youre most likely to ovulate during this five-day range. If youre one of the many women who have a 28-day cycle, theres a good chance you’ll ovulate on day 14. (Day 1 is the first day of your period; day 28 is the last day before day 1 of your next period.)

A more accurate way to figure out when you ovulate is to track the patterns in your body temperature and your vaginal discharge for a cycle or two. Its natural and free, but it takes time and effort.
If you pay attention to these cues and jot them down each day, you may start to see a pattern that can help you predict when youll ovulate next.
Body temperatureYou wont feel the change, but a few days after you ovulate, your basal body temperature rises. (Your basal body temperature, or BBT, is your lowest body temperature in a 24-hour period.) This tiny uptick is only 0.4 to 1.0 degree Fahrenheit. You can detect it by taking your BBT every morning with a special thermometer.
Vaginal dischargeThe discharge youll be tracking is cervical mucus, which changes substantially during your cycle. For most of the month, you may have very little of it and feel dry. But as you approach ovulation, youll notice much more cervical mucus. Itll be clear, slippery, and stretchy – kind of like raw egg whites.
Mild cramping
Some women report that they feel mild cramps or twinges of pain in the abdomen or a one-sided backache around the time of ovulation. This sensation is known as mittelschmerz.
