How does natural family planning work?
Two methods of natural family planning are currently taught. The first is the mucus or ovulation method. In this method, the days just before and just after ovulation are determined by checking the woman’s cervical mucus. When a woman is most likely to become pregnant, the cervical mucus is stretchy, clear and slick. The mucus during this time looks and feels much like an uncooked egg white. The second method is called the symptothermal method. With this method, the woman takes her temperature each day with a basal body temperature thermometer and writes it down on a chart. At the time of ovulation, a woman’s temperature will rise slightly (about .9°F). The woman also checks the consistency of her cervical mucus like she does with the mucus method. She may also notice other changes, such as pain in the area of the ovaries, bloating, low backache and breast tenderness. In both methods, couples use a chart to keep track of the changes in the woman’s body.
