Accurate Tracking

Through Cervical Fluid sensing technology, kegg predicts your unique peak fertility.

Personalized For You

kegg’s algorithm provides fertility predictions that are unique like you.

Not another BBT tracker. kegg uses cervical fluid.

Cervical fluid is the key sign to knowing your fertile window and peak fertility. Within your fertility cycle, hormonal fluctuations create changes in the electrolyte levels of your cervical fluid. These changes can be detected through impedance. kegg senses these daily changes and displays them to you in actionable results.

How do I read and interpret my kegg readings?

kegg is an intuitive fertility tracker that measures changes in electrolyte levels of cervical mucus —the golden metric to pinpointing your fertile window within each menstrual cycle. By using advanced sensing technology known as impedance, kegg can detect your fertile window using your unique cycle data.

Following the daily reading, which takes around 2-3 minutes, kegg will send your kegg data to the cloud for analysis. In real-time, the device connects to a mobile app that displays your reading results, cyclical trends, and fertility predictions. With consistent, once-a-day use, you will gain deeper insight into your own unique fertility pattern.

Does kegg work for women diagnosed with PCOS?

Many women with PCOS share that tracking their fertility is especially challenging. While kegg has not been clinically tested on women with PCOS, there is a growing number of women with PCOS who turn to kegg to successfully track their fertility.

Can I use kegg as a natural contraceptive method?

kegg is not recommended as a contraceptive device. kegg can be used as a complementary tool to your preferred fertility awareness-based method (FABM). The kegg algorithm is not to be used as a birth control tool. The kegg algorithm has not been designed nor tested for pregnancy prevention. You can use kegg data and trends to compliment your own primary choice of fertility awareness method.
