How It Works
kegg Fertility Tracker & Kegel Ball is ideal for women who want to maximize their chances of conception. kegg gives the confidence of fertility tracking through cervical mucus sensing technology in only 2 minutes a day.

kegg™ is an FDA-registered fertility tracker that senses cervical fluid—the key indicator to predict your fertile window and when you’re most likely to conceive. By using advanced sensing technology known as impedance, kegg can help detect your peak fertility and plan ahead with confidence.

Is kegg right for me?
Wearable trackers can be annoying and disrupt your lifestyle. kegg fits seamlessly into your routine, and there is no need to wear it overnight. Following a daily reading—which takes only two minutes to complete—kegg will send your data to the cloud for analysis. In real-time, the device connects to a FREE mobile app that displays daily fertility status, cyclical trends, and fertility predictions.

Fertility predictions are unique to each woman. With consistent use once a day, you will gain personalized insights into your own fertility pattern. kegg will be at your side and nothing will be left up to chance.

About the Brand

kegg's mission is to live in a world where women are empowered by knowledge about their bodies.

Created for and by women who've been there, we understand that women’s fertility is more complex than just a “28-day cycle” and many of us don’t ovulate on Day 14. That’s because we are cyclical beings. At kegg, we approach problems with both compassion and rigor — from our diverse team of engineers, physicians, and designers.
