Baby Month: OvaCue Fertility Monitor

The OvaCue Fertility Monitor predicts ovulation up to seven days in advance using the patented Electrolyte Method – a technique that has been demonstrated to be 98.3% accurate in predicting ovulation.

Here’s how it works:

The OvaCue consists of a hand-held monitor with a color screen, a spoon-sized oral sensor, and an optional vaginal sensor (sold separately). Throughout your menstrual cycle, the electrolyte (minerals such as sodium and potassium) levels in your saliva and cervical mucus fluctuate as the hormone levels in your body change. Starting with Cycle Day 2, you will use the oral sensor each morning to measure the electrolyte levels in your saliva. The OvaCue will store the information gathered from these oral readings, track the changes in electrolyte levels in your saliva during your cycle, and process this information to precisely define your time of peak fertility.

When I first started using the OvaCue Monitor I was completely confused! I later learned to not follow the cute little colored boxes on my first cycle. Since I am someone who obsess over everything my first cycle I decided to use the OvaCue , OPKs and to chart.

I am glad I decided to temp and chart because then I would really have been confused! As you can see the OvaCue said I ovulated on Oct. 20th, but I didn’t ovulate until Oct. 27th. While I can see the OvaCue saying I ovulated, because to my chart my body definitely geared up to ovulate but didn’t. I don’t have screenshots of the OvaCue after the 23rd, but I did continue using it and eventually I was able to read my numbers by looking for the cue peak in my oral readings, and then finding my high vaginal reading and sure enough 3/4 days after my highest vaginal reading I ovulated.

With the OvaCue Fertility Monitor and charting I did get pregnant! Unfortunately it ended in an early miscarriage. I finally got my first AF (menstrual cycle) since the miscarriage and silly me forgot to start using the OvaCue on CD2, I started on CD7 and I know that is why my cue peak and confirmation are 2 days off. But, since I do know how to read the OvaCue readings I can see that I did ovulate on CD14 even though the OvaCue says CD16

Now I know that if I had done my readings starting CD2 like your supoose to it wouldn’t have been off by 2 days. I am excited to see both charts look pretty much the same! The only thing is I never did get a positive OPK (ovulation predictor kit). Although the evening of CD13 I got one OPK that was darker than the tests the past few days, so I could have missed the surge during the night.

The OvaCue works! While it doesn’t MAKE you get pregnant, it does help you know days in advance that ovulation is approaching which gives you more time to have sex and to time it better.

What Do The Numbers Mean?
The OvaCue Fertility Monitor uses the patented Electrolyte Method™ to measure changes in the electrolyte levels in your saliva and cervical mucus. These characteristic changes signal the onset and completion of ovulation. As your body moves through its monthly cycle, the levels of various hormones circulating in your body go up and down, and these hormonal fluctuations produce changes in the electrolyte characteristics of your saliva and cervical mucus. Using measurements obtained from the oral and vaginal sensors, the OvaCue® produces a numerical reading that reveals the relative trends in electrolyte levels. This allows the OvaCue® to identify when the hormonal changes that signal ovulation have occurred.

Oral readings:
About a week before ovulation occurs, a high oral reading followed by two lower oral readings will be detected, which is called the Cue Peak. Once the Cue Peak is detected, the OvaCue® can then predict, several days in advance, your most fertile days.

Vaginal readings:
When using the optional vaginal sensor, the OvaCue® tracks changes in the electrolyte levels in the cervical mucus. This allows the monitor to detect the estrogen surge that occurs just prior to ovulation, and the subsequent shift from estrogen to progesterone dominance that coincides with ovulation. In the days just prior to ovulation, your vaginal readings will be relatively low. Low vaginal readings reflect high estrogen levels, and indicate high fertility. Once ovulation occurs, your vaginal readings will increase, indicating the shift to progesterone dominance and the end of
your fertile window.

  1. Oh my goodness, with all the new “baby” technology coming out we won’t need to go to the doctor for prenatal care anymore 🙂
