Pink colors indicate your period (light or heavy flow).
Phase 1 is yellow and is generally non fertile.
Phase 2 is green and is a fertile time.
Dark green signifies the PeakDay of fertile mucus.
Phase 3 is purple and is a non fertile time.

PeakDay uses experience, algorithms and a scientifically-based method to calculate your fertility.

For 50 years, CCL has used the Sympto-Thermal Method for natural family planning.
For 10 years, the CycleProGo app used the STM method and algorithm to help thousands of couples with their fertility.
