Optional Charting Methods

As a couple there are many factors to consider when selecting an NFP method. Below are brief overviews of each method. Visit the provided websites for more information.

Billings Ovulation Method

The Billings Ovulation Method® (BOM) is a simple yet scientific method of Natural Family Planning. Ongoing research has been conducted in Australia, Sweden and Spain since it was developed over 50 years ago by physicians John and Lyn Billings of Melbourne, Australia.

Couples using the Billings Ovulation Method® track the woman's natural and unique signs of fertility and infertility each day. Based on the primary observation of sensation, four simple rules are applied within the woman's cycle (the first three rules are used before ovulation and the fourth rule is applied once the fertile phase is over) based on a couple's desire to achieve or postpone for a just cause. As published in numerous journals, the Billings Ovulation Method® is 99.5% percent effective in postponing pregnancy, providing couples follow the guidelines correctly.

Sympto-Thermal Method by CCL

The Sympto-Thermal Method (STM) taught by the Couple to Couple League (CCL) is based on three key signs of fertility: cervical mucus, basal body temperature and changes in the cervix. By observing and recording these signs you and your spouse will be able to identify Phase I, II and III and therefore know if you’re in a time of fertility or infertility.

These signs are easily noticed by any woman who has learned to watch for them. It takes only a minute or two each day to record them in CCL’s mobile app, CycleProGo, or on a paper chart. The chart provides a daily record that can be used to identify the days of fertility and infertility. Once the fertile and infertile days have been identified, couples apply “rules” that they learn in class (and that are explained in CCL’s Student Guide) to frame the boundaries between the phases of the cycle.

Creighton Model FertilityCare™ System

The Creighton Model FertilityCare™ System (CrMS) is a standardized modification of the Billings Ovulation Method, and utilizes the new women's health science of NaProTECHNOLOGY. CrMS relies upon the standardized observation and charting of biological markers that are essential to a woman's health and fertility. These 'biomarkers" tell the couple when they are naturally fertile and infertile, allowing the couple to use the system either to achieve or to delay pregnancy. These biomarkers also telegraph abnormalities in a woman's health.

The CrMS is based upon a couple’s knowledge and understanding of their naturally-occurring phases of fertility and infertility. Through this understanding, the couple is able to make decisions (choices) regarding the achievement of pregnancy. This system provides information which deals with the complete dimension of their procreative ability. In addition, it provides women the added benefit of being able to monitor and maintain their procreative and gynecologic health over a lifetime. It is truly the only family planning system which has networked family planning with gynecologic and procreative healthcare and health maintenance. The teachers of the CrMS are trained allied health professionals and specifically-trained physicians have been educated to incorporate the CrMS into their medical practice.
