If you have irregular cycles and/or PCOS, you need to monitor your fertility in real time as it changes cycle to cycle. kegg was designed to track your fertility in real time each cycle to spot your full fertile window.

Conventional fertility tracking methods can be especially frustrating because the fertile window does not fall consistently at the same time. kegg allows you to see a potential fertile valley open as your readings move downwards, allowing you to make actionable decisions. Additionally, with kegg, you only pay once and don’t worry about monthly costs on strips as there are no additional monthly costs.

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. What is unique about kegg is that instead of focusing on the day of ovulation (which is only one day when you are fertile) kegg focuses on identifying your whole fertile window. Knowing your full fertile window and optimally timing intercourse/insemination can quadruple your chances of getting pregnant.

Yes! And there are many stories of women in their 40s who successfully conceived using kegg. 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.

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.
