Basal Body Temperature (BBT) Tracking
To track your basal body temperature, you will need a basal body thermometer. Use this thermometer everyday around the same time upon waking each day, before getting up and moving about. Next, record your temperature in order to track your temperatures throughout the cycle.
In the follicular phase, or the timeframe between your period and ovulation, temperatures fluctuate but generally remain low. Then, after ovulation, temperatures rise and stay elevated until progesterone begins to descend and ushers in the start of the new cycle, or your period.
Confirming Ovulation with BBT
- Tracking your BBT consists of taking your temperature immediately upon waking everyday and recording the value.
- A common method used to confirm ovulation consists of having three consecutive temperatures at least .2˚F higher than the previous 6 measurements.
- BBT tracking does not give the user notice of the fertile window opening. Instead the user can see when ovulation has passed and the fertile window is closing.
Tracking Cervical Fluid with kegg
There are many methods for tracking the changes in the cervical fluid. Manual observation methods require several months of training and practice before a user becomes proficient in identifying their cervical fluid. kegg allows a user to successfully track their cervical fluid starting on day one. Instead of assigning qualitative labels to the type of mucus, kegg detects the changes in electrolytes in the cervical fluid, allowing the user to see the full fertile window.
Your fertile window and kegg
The rising progesterone which primarily occurs after ovulation causes a distinct shift in the electrolyte concentration in the cervical fluid. This change results in a rise in the kegg readings. When the user sees this rise, she can suspect that ovulation occured on the day of the rise or the day before the rise.*
- Tracking your cycle with kegg consists of taking your two minute reading once a day within the same two hour window (morning or evening)
- kegg detects the changes in the cervical fluid allowing the user to see the full fertile window
- After ovulation, there is a rise in the kegg readings indicating the fertile window is coming to a close

Tracking with kegg
*Note: kegg alone cannot confirm ovulation. Instead, if a valley was successful for ovulation, the user can suspect it occurred on the day of the rise or the day before the rise when exiting the fertile valley.
