Ovulation Calendar: Chart Your Ovulation

Written by Michelle

We’re all vaguely familiar with the term “ovulation,” realizing it’s a process that happens in our bodies once a month and that it has something to do with having babies. But what exactly does the term “ovulation” mean, and how can pinpointing ovulation with an Ovulation Calendar help us to get pregnant faster, or to avoid pregnancy?

What is Ovulation?

ovulation calendarDuring ovulation, which occurs about once a month, a single egg is released from the ovaries. Once released, the egg has a window of up to 48 hours during which it can be fertilized by sperm. After that, it begins to disintegrate. If the released egg is fertilized and successfully implants in the uterus, the result is pregnancy.

During ovulation, your chances of getting pregnant are highest. Your fertile period is actually longer than 48 hours and in fact starts each month about 4 to 5 days before ovulation, because sperm can live in your body for approximately 4 to 5 days. But the fertilization itself can only happen once the egg is released.

Understanding when you ovulate can help you either achieve pregnancy or avoid pregnancy – depending on your goal. Either way, it’s a good idea to learn to listen to your body and to understand the hormonal and physical changes that it is going through every month.

What is an Ovulation Calendar?

If you’re interested in pinpointing your ovulation, an Ovulation Calendar can be very useful. An Ovulation Calendar is a software program that calculates your time of ovulation and generates your personal fertility calendar. Simply enter the length of your menstrual cycle and the start date of your last period, and the Ovulation Calendar will calculate your fertile and your non-fertile days and present them on a color-coded calendar.

What if my periods are irregular?

An Ovulation Calendar helps you to predict your most fertile time of the month so that you can either achieve, or avoid, pregnancy. Obviously, an ovulation calendar works best for women with a regular menstrual cycle. Irregular cycles are harder to predict, so if your cycle is highly irregular, you might want to use other methods of predicting your ovulation, such as using ovulation prediction kits or fertility monitors.

    It's funny that this article shows a photo of a thermometer, with no mention of what it is for. Ovulation calendars that only require you to enter your last menstrual period and your cycle length are not helpful for many women. They simply GUESS when you ovulate based on a typical cycle.

    In order to know for sure when you ovulate, you can keep track of your basal body temperature (your temperature upon waking in the morning before you get up). The day after you ovulate, your basal temperature rises. Websites such as Fertility Friend provide way more helpful information and a free way to chart online.
