Case reports of the Marquette method.

The Marquette method (MM) is a flexible system whereby patients can use cervical mucus and temperature observations in conjunction with the ClearBlue Fertility Monitor (CBFM) an algorithm to clarify the beginning, peak, and end of the fertile window. Two cases are presented which illustrate useful aspects of the MM. The first case involves a couple who have not had success with a Diocesan sympto-themal method and find the objective nature of the CBFM to be critical in sustaining their commitment to natural family planning (NFP). The second case examines a couple in the breastfeeding/weaning period using the Marquette Breastfeeding Protocol. It is the author's hope that these case presentations increase the Catholic Physician's desire to learn more about NFP.
