How kegg Helps You Detect Your Fertile Window with Cervical Mucus Sensing Technology

By kegg Team

Trying to conceive can often feel like a mystery. But understanding your fertile window doesn't have to be guesswork. kegg is a revolutionary 2-in-1 fertility tracker that offers real-time insights into your unique cycle powered by advanced sensing of cervical mucus changes through impedance technology. In just two minutes a day, kegg helps you identify your fertile window so you can plan with confidence.

Cervical Mucus: Your Body's Natural Fertility Indicator

Cervical mucus is one of the most important yet overlooked signs of fertility. Its consistency, volume, and composition change throughout the cycle in response to the various hormone shifts. These changes are nature’s way of signaling when the body is preparing for ovulation.

As estrogen rises before ovulation, cervical mucus becomes more abundant and slippery, ideal for nourishing and transporting sperm. In fact, research shows that cervical mucus is one of the strongest predictors of conception. The most fertile cervical mucus typically appears 2–3 days before ovulation, the days when you are most likely to conceive. Research also shows that cervical mucus begins changing before hormone changes can be detected in blood or urine, suggesting it is one of the most reliable indicators of fertility.

However, tracking cervical mucus manually can be subjective and imprecise. That’s where kegg comes in.

How kegg Works: Advanced Technology That Matches Your Body's Rhythm

kegg uses a cutting-edge sensing method called impedance technology, a method widely used in biomedical diagnostics. This allows kegg to detect even subtle changes in the composition of cervical mucus, allowing users to pinpoint all of their fertile days and recognize their best days to try to conceive.

During your daily 2-minute reading, kegg sends a low-level electrical pulse and analyzes how that signal is returned. This response changes as your cervical mucus changes. The result? A non-invasive, real-time fertility tracking experience that helps you spot your most fertile days which occur before ovulation.

Your fertile days begin 5 days before ovulation. During that time, your cervical mucus becomes a sperm-friendly place to be. It becomes wetter, more slippery, and less resistant to kegg’s signal. The result? Your kegg impedance trend forms a valley. The trend begins to move downwards on the cycle chart. This is your real-time indicator that it is an ideal time to start baby dancing. Unlike other methods which display various hormone ratios, kegg gives you the metric required to time your efforts with confidence: the fertility of your cervical mucus.

Real-Time Fertile Window Predictions: Personalized and Smart

Temperature-based methods that confirm ovulation after it’s already passed. But, kegg? It focuses on identifying all of your fertile days, and also predicts them in advance because understanding your data in real-time and having advanced predictive notice is helpful and insightful.

What You’ll See in the App:

Fertility and Cervical Mucus Score - a score 0-100 which predicts the likelihood each day is fertile. The higher the score, the more likely that cycle day is fertile.
Your predicted fertile window outlined in green.
Predicted peak fertility window
Daily fertility status
Ovulation probability
