OvaCue Fertility Monitor Vaginal Sensor
The Ovacue vaginal sensor must be used with the OvaCue Fertility monitor. The vaginal sensor is highly recommended for women with with irregular cycles or ovulatory disorders (such as PCOS).
The sensor measures electrolyte changes in vaginal mucus, just as the oral sensor measures electrolytes in saliva. With these measurements, OvaCue will mark the end of your fertile window and confirm ovulation by recording the change from estrogen to progesterone dominance.
