natural family planning
2. A kind of fertility awareness in which a woman plots on a graph her daily basal body temperature, cervical mucus characteristics, and common subjective complaints associated with ovulation, e.g., mittelschmerz, to identify the days of the menstrual cycle during which there is the highest potential for conception.
