The CREIGHTON MODEL Vaginal Discharge Recording System. Build each
observation from a bleeding marker and/or a discharge code, add color and
consistency descriptors, then note how often the most fertile sign was
seen. Peak-type mucus is any discharge that is clear,
stretchy, or lubricative; the Peak Day is the last such
day in a cycle.
