1. A method for determining menstrual cycle phase comprising the steps of:

  • a. inserting a probe having an inner bearing element at a working end into a cavity for obtaining a viscous mucus sample, and inner bearing element carrying said mucus sample;

    b. removing said probe from the cavity;

    c. placing said inner bearing element within an outer bearing element;

    d. constraining said inner bearing element within said outer bearing element for relative movement therebetween;

    e. biasing said probe for indicating menstrual cycle phase by relative movement between said inner bearing element and said outer bearing element, said probe biased with sufficient force to cause relative movement between said inner bearing element and said outer bearing element when the viscosity of said mucus sample is low and with insufficient force to cause relative movement between said inner bearing element and said outer bearing element when the viscosity of said mucus sample is high.
