The fertility calendar method is a way to monitor your ovulation so that it improves your chances of having a child. It’s an effective way to work with nature to conceive.
Many women who want to have a child are unaware of a simple biological fact: the female body has a biological mechanism for timing its ovulation. Moreover, since sperm can continue to be active for five days after you have sex, it’s possible for a sperm to survive until the release of an egg.
Understanding your fertile days, then, is based on understanding the ovulation cycle. The better it is understood, through the process of tracking ovulation, the higher your chances of getting pregnant. You can identify your most fertile days by figuring out your own fertility cycle.
Ideally, you should work with a fertility specialist or fertility clinic as you develop your fertility calendar as they will guide you on what information to notice and will help you interpret the information that you collect over time.
Set Realistic Expectations
Although it’s easy to get the impression that the Fertility Calendar is completely logical, even mathematically accurate, it doesn’t actually work that way. Calendar your fertility to make an educated guess rather than expecting to come up with an exact date. What’s more, the pattern that you detect will not consistent from one month to the next. It fluctuates between a few days.
Despite the possibility of errors in predicting when ovulation will occur, the Fertility Calendar Method is far more effective than relying on random chance when it comes to deciding on the best days to have sex during the course of a month to get pregnant. An educated guess based on tracking your cycles is far more likely to be successful than no guess at all.
Understanding that the method is based on estimation rather than calculation allows you to be patient as you practice it.
How to Use the Fertility Calendar Method
The purpose of the fertility calendar is to help you identify when you menstruate and when you ovulate. You can track the duration of each cycle with a printed calendar or by using an app.
Essentially, there are three broad steps to take to develop a useful Fertility Calendar:
First, mark the first day you have your period with the abbreviation “CD1,” which simply means “chart day one.”
Second, mark down each day you menstruate. You can, if you like, also keep a journal that correlates with your calendar to notice when your period is heaviest and when you have cramps or any other relevant information. While it is not necessary to keep a journal to use the fertility calendar method, it can be useful in helping you notice menstrual patterns.
Third, keep track of information that will help a fertility specialist get a better understanding of how to review all the information you have gathered through observations. Some important things to track are when you have sex and when you have PMS symptoms (cramps, headaches, backaches, etc.)
Instead of relying on mood or random luck to determine when to have sex for the purpose of becoming pregnant, the Fertility Calendar Method helps you plan the best days and time. By monitoring your fertility cycles, you will detect the pattern of your most fertile days and least fertile days. Think of this information as a way of recognizing your fertility window, the brief time each month when you are most likely to get pregnant.
While, of course, you can track the cycles on your own, it is helpful to work with a fertility expert, who can help you interpret your experience and explain the best way to collect and organize your observations.
