kegg fertility tracker and app

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.

Worked with my PCOS

“I have irregular cycles due to my PCOS. I was able to see that I was actually ovulating a couple of days after my shift temp started, which allowed us to successfully conceive. I don't think we would've been successful had I not had my kegg!”

Absolutely! kegg can help you confidently track your fertility, allowing you to optimally time intercourse/insemination. Many women who have been trying to conceive for years have been successful, thanks to kegg.

Knowing your full fertile window and optimally timing intercourse/insemination can quadruple your chances of getting pregnant.

Kegg is recommended for women in their reproductive years, 21 years or older, who ovulate and have cycles. kegg helps women identify their fertile window in order to optimally time their trying to conceive efforts. 

Many women in their 40s report that by using kegg they feel more confident they are maximizing their chances of conception as they are not missing valuable days of the fertile window, when compared to using other fertility tracking methods, such as detecting the LH surge or recording their basal body temperature. Every egg counts and with kegg, you can be sure you are timing your efforts accurately.
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.

ollowing 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.

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.
