Fertility awareness-based methods are a form of natural family planning. These methods require you to keep track of your menstrual cycle to determine the days that you can get pregnant.
Fertility awareness-based methods are inexpensive. They are also hormone-free. These methods can be used for birth control. They are also a good way to know your body better. You will notice changes and better understand your menstrual cycle.
Types of fertility awareness are:
Standard Days (SDM): you can use this method if your menstrual cycle is between 26 and 32 days long. You will need to record your periods and determine when you cannot get pregnant.
TwoDay (TDM): for this method you need to observe cervical discharge to see when you are fertile.
Cervical Mucus: your body makes a specific goo when you are most fertile. This method is about tracking your cervical mucus.
