How does the Symptothermal Method of natural family planning work?
This method uses a combination of BBT (basal body temperature) change and change in cervical mucus, or other cyclic symptoms. A chart of symptoms and basal body temperature is helpful in identifying the fertile days. Some women are aware of ovulation discomfort (Mittelschmerz), which may also be incorporated into the charting. Pain may occur just prior to, during or just after ovulation. The couple is not protected from sexually transmitted diseases including HIV.
