Presented here is a safe, non-invasive, and effective method of birth control based on the recording and interpretation of signs and signals from a woman's own body. This includes:
* charting the waking temperature
* noting changes in the cervical mucus
* keeping a menstrual calendar

Observing these natural signs of fertility, a woman can have an alternative to the medical approach of hormone treatments or surgery. With the willingness to keep track of their mutual fertility, and act accordingly, a couple can share the responsibility of family planning.
