RRM Academy Synopsis

Creighton Model charting rules change after the pill and postpartum

A 2004 textbook chapter on the Creighton Model System (CrMS) explains how its charting rules adapt to special situations. The chapter sets out special CrMS instructions for post-pill, breastfeeding, postpartum and premenopausal women. Sample charts illustrate many of them.

Key Findings

  • The chapter treats coming off birth control pills, breastfeeding, postpartum, pregnancy loss, premenopause and sterilization as separate categories. Each has temporary instructions until the basic instructions restart.
  • For women coming off birth control pills, the chapter attributes irregular ovulation and cervical erosion to aftereffects of pill use. The chapter calls persistent post-pill anovulation a possible cause of infertility.
  • The chapter separates total from partial breastfeeding. Suckling suppresses ovulation, possibly for an extended period, the chapter states. In breastfeeding women, fertility can return before menstruation.
  • For infertility, the chapter says CrMS charts help time tests. The authors describe dry, limited mucus and regular mucus cycles as preliminary patterns, with limited mucus cycles seen most often.
  • The chapter defines a "double" Peak as two Peak-type mucus buildups in one cycle, linked mainly to acute stress. Separate rules cover seminal fluid, arousal fluid and premenstrual mucus.

RRM Context

A chart gives restorative clinicians a daily record of mucus and bleeding that reflects ovarian function. The record looks different after suppressive medications, after pregnancy and near menopause. Teaching programs therefore write separate rules for each state. This chapter appears in a NaProTECHNOLOGY textbook, where the chart also helps time tests.

Abstract

This chapter describes the special instructions of the CrMS, which apply temporarily in particular reproductive categories until the basic system instructions are restarted. The categories covered include coming off birth control pills, total and partial breast feeding, the postpartum period without breast feeding, post-abortion, the single woman who is not genitally active, premenopause, post-sterilization, and infertility. Hilgers also gives instructions for particular situations, including the seminal fluid and arousal fluid instructions, early ovulation, the “double” Peak, long cycles, anovulation, premenstrual mucus and spotting, and dry cycles, and reports that a study of 564 menstrual cycles found an incidence of “double” Peak of 7.8 percent. For couples with infertility, the chapter describes dry, limited mucus, and regular mucus cycle patterns and the use of the chart to time evaluation tests such as hysterosalpingography, progesterone levels, and endometrial biopsies.
