Understanding the Purple Box
With the vaginal sensor, OvaCue Mobile tracks changes in the electrolyte levels of the cervical
mucus, which allows the monitor to detect the shift from estrogen to progesterone dominance that
accompanies ovulation. When this shift occurs, you may see an increase in the vaginal readings
(called the Vaginal Rise) and your fertility prediction will change to pink. After the monitor detects a
rise in the vaginal readings, it will expect the vaginal readings to remain elevated, which confirms
that ovulation occurred successfully and that you have entered the luteal phase of your cycle.
If, after the Vaginal Rise (pink day), OvaCue Mobile detects a dip in your vaginal readings, and
then a subsequent rise in your vaginal readings, you will see the purple fertility prediction appear.
Because both the pink and purple days can represent ovulation, it will be necessary to do some
data interpretation to determine which day represents the day that you actually ovulated. The
appearance of the purple day suggests that your vaginal readings for the current cycle did not
follow the typical pattern of remaining elevated after the first Vaginal Rise. There are a number
of possible explanations for why vaginal readings might dip, and then increase again, including
hormonal fluctuations or the occurrence of secondary fertility (multiple follicular stimulation). For
