Vaginal Discharge Recording System (VDRS)

The Vaginal Discharge Recording System (VDRS) is the standard way a woman records what she sees and feels at the vulva each day.¹ It is the charting framework of the Creighton Model FertilityCare System.¹ The woman observes the outside of the vulva through the day. She records bleeding, days with no discharge, and any cervical mucus that is present. Each day receives a short code. The code describes how the mucus looks, how far it stretches, its color, and how it feels.²

The design purpose of the VDRS is one shared language. A chart made by a woman in one city reads the same way as a chart made by a woman elsewhere. A FertilityCare Practitioner can read the chart and identify the Peak Day. The Peak Day is the last day of mucus that is clear, stretchy, or slippery at the vulva.³ It is the main marker on the chart because it closely tracks ovulation.³ The practitioner can also follow mucus quality across the cycle. The practitioner can flag signs of a hormone problem without asking the woman to repeat her history.⁴

The daily codes are the raw material for deeper review. Clinicians calculate the Mucus Cycle Score from VDRS entries. In NaProTechnology, clinicians time blood tests and surgery to the cycle. That timing depends on accurate VDRS records. A clinician cannot read a chart with loose or uneven coding with confidence.²

Careful records also make fertility charting a long-term health tool rather than a snapshot of one cycle. Patterns across many cycles carry real information. Changes in mucus quality over time become visible only when every cycle uses the same codes.
