This model features the same sensitive electronics for monitoring changes as the OvaCue does in your body, however it works better for women who have cycles that are very irregular and unpredictable.
Users of the Cue II, predecessor to the OvaCue, need to obtain Cue Charts and learn how to track and interpret their readings. This is explained in detail in the Owners Manual.
In brief, the user plots a numeric reading on a Cue chart each day. About a week before ovulation, electrolytes such as sodium and potassium appear in elevated amounts in the saliva. It is this Cue Peak on the graph that announces the beginning of the ovulatory process.
A few days after the Cue Peak, the luteinizing hormone (LH) in the blood increases and decreases very sharply over a period of 24 hours (the LH peak). As LH reaches its peak in the blood, there is a definite change in the reproductive tract which can be measured by the (optional) Cue vaginal sensor. Mucus secretion increases, and the electrolyte content of the mucus changes. This change causes a sharp, clear drop and increase in these readings. It is this nadir that the Cue uses to confirm ovulation.
