NATURAL FAMILY PLANNING

This is also known as fertility awareness or periodic abstinence. For this method to work, a man and woman cannot have sex on the days the woman can become pregnant unless using another form of birth control. These days usually include from seven days before the woman ovulates (releases an egg) to three days after she ovulates. A woman can ask her doctor how to tell when she ovulates. This is done by taking into account when the last menstrual period began, changes in body temperature, and changes in vaginal mucus.
