For the last 5 cycles, I have been using the Kegg device that reads the electrolyte levels present in the cervical mucus in the vagina. To use this device, someone would insert Kegg in the same two hour period of time during the day. Kegg takes approximately two minutes to give the user a reading on the graph.

This product is an exciting development in the femtech field because it actually does read a real-time fertility sign. Cervical mucus is completely necessary for natural conception to occur. Without the presence of cervical mucus in the cervical crypts, sperm cannot to get to their destination to reach the egg. For this reason, anyone trying to conceive needs to track cervical mucus or use an alternative device such as Kegg (or a device that reads estrogen levels) in order to time intercourse for when they are most likely to conceive.
Here is what a Kegg chart looks like while lined up with my real-time Billings Ovulation Method cervical mucus observations.
Who is Kegg right for?
I know that the question on everyone’s mind is whether Kegg can be used to re-place cervical mucus observations for avoiding pregnancy. Unfortunately, the answer is that Kegg is not suitable for avoiding pregnancy. It is designed to find the most suitable days for conception. For those avoiding pregnancy, the fertile window has to be much longer than the window that Kegg gives. Until Kegg has been studied for pregnancy avoidance, I cannot recommend it as an alternative to cervical mucus checks which must be made multiple times of day until the evening when someone is strictly avoiding pregnancy.
Kegg may be right for someone who wants to conceive without needing to take a class or read a book on cervical mucus. In my experience, for the most part, it detected my most fertile days in a way that would likely lead to conception if used.
Kegg may not be right for you if you have a very erratic schedule. Since it has to be used in the same two hours and cannot be used up to 8 hours after sex, this may make Kegg harder to use. I personally experienced some issues timing Kegg correctly because of the nature of practicing a fertility awareness method meaning that I have sex at different times of the day based on what part of the cycle I am in.
My 5 Cycles with Kegg
The following images are my five cycles with the Kegg device compared to urinary hormones and cervical mucus observations. The three chicks in the egg represent the three most fertile days with Kegg. All of the charts are from Read Your Body by the Body Literacy Collective.
My Overall Impression of Kegg
I am often very critical of femtech that gives predictions, and Kegg does give calendar predictions at the beginning of the cycle. However, overall, I believe that the readings I got with Kegg did line up with my real-time signs for the most part. Since this device is for conception purposes, it does seem to highlight the most fertile days. I did have to switch from mornings to evenings on my Kegg readings to get clearer charts. I also find Kegg extremely hard to use in my luteal phase when sex may occur at any time of day, but this isn’t a huge problem since you can stop using Kegg once it has detected your rise. For those who want to add an extra layer to your chart or chart to conceive only, I can recommend the Kegg device.
Customer service with Kegg has been excellent. The team is very reachable. If you would like to see more Kegg charts and learn from fellow Keggsters, you may join the Kegg facebook group for conception or for those using it along with signs to avoid.
