<unk>  (FA) refers to a set of practices used to determine the fertile and infertile phases of a woman's menstrual cycle.<unk>  methods may be used to avoid pregnancy, to achieve pregnancy, or as a way to monitor gynecological health. Methods of identifying infertile days have been known since antiquity, but scientific knowledge gained during the past century has increased the number, variety, and especially accuracy of methods. Systems of<unk>  rely on observation of changes in one or more of the primary<unk>  signs (basal body temperature, cervical mucus, and cervical position), tracking menstrual cycle length and identifying the fertile window based on this information, or both. Other signs may also be observed: these include breast tenderness and mittelschmerz (ovulation pains), urine analysis strips known as ovulation predictor kits (OPKs), and microscopic examination of saliva or cervical fluid. Also available are computerized<unk>  monitors.
