NFP/FABM Training & Educators

NFP/FABM Educators are listed below according to the method taught to achieve or postpone pregnancy. Most offer classes, both online and in-person that cover the science and biology, how to use the method, the Church’s teaching, and basic charting. 

While there are many effective NFP methods and instructors available, the three methods of NFP that the Archdiocese of New York supports include the Cervical Fluid methods, the Sympto-Hormonal methods, and the Sympto-Thermal methods listed below, along with the independent organizations who provide training in these methods.

For assistance in discerning which method might be best for you, or which technologies work best with a particular method, feel free to contact Cassie Moriarty (Fertility Educator) at or 803.606.2121.

Cervical Fluid Methods

The Billings Ovulation Method (BOM) is based on a woman’s daily observations of cervical fluid (also known as cervical mucus). For additional information on the BOM, visit:

For training options available, visit the following sites:

  • by The Marriage Group, LLC
  • by BOMA-USA
  • St. Augustine Foundation’s “Catholic Couples NFP” no-cost program.  For more information, visit or call 888-899-8884.

The Creighton Model FertilityCare System (CrMS) is a comprehensive method for tracking a woman’s fertility by teaching her to understand the cervical fluid or mucus observations throughout her cycle. The Creighton method also serves as a tool for evaluating and monitoring a woman’s reproductive and gynecologic health through the new science of Natural Procreative (NaPro) Technology. For additional information on the CrMS, visit:

Sympto-Hormonal Method

Sympto-Hormonal Methods (SHMs) incorporate cervical fluid observations with a second sign, for example, urinary metabolite hormone levels, to identify days of fertility. The SHMs that we endorse include:

FEMM (Fertility Education & Medical Management) teaches women the link between hormones and health, and helps them to understand and identify ovulation as a sign of health. Women learn how to identify normal or abnormal health patterns, as well as how to use this information to manage their fertility (achieve or avoid pregnancy). FEMM can also be used as a method of natural family planning. 

To view and register for classes, visit where you will find longer day sessions and shorter segmented sessions (same content is provided in different approaches).

The FEMM app assists women and couples in tracking their health and fertility data, as well as physical and emotional symptoms. The app provides individual, personalized information and feedback, helping women to know:

  • the average length of their cycle
  • quality and length of their bleeding
  • point of ovulation at each cycle
  • fertility window and more

Currently available in English and Spanish, the app can be downloaded for free from the Android and Apple stores. 

For your information, here are some website and social media links:

The Marquette method of NFP helps women and couples to find their fertile window and understand the woman’s menstrual and reproductive health by interpreting biological signs of fertility.  These signs of fertility are manifested in the activity of reproductive hormones found in urine, changes in cervical mucus and/or fluctuations in basal body temperatures. The purpose of using natural biological signs of fertility is to help women and couples to identify the day closest to ovulation and accurately estimate the fertile window.

The Marquette Method (MM) uses a hand-held electronic fertility monitor (such as ClearBlue) to measure hormones levels (at home) in the woman’s urine.  The monitor helps the woman estimate the beginning and end of the fertile time in her cycle. The information from the monitor can be used with observations of cervical fluid, basal body temperature, or other biological indicators of fertility.

Sympto-Thermal Methods

The Sympto-thermal Method (STM) is based on a woman’s observations of her cervical fluid, basal body temperature (waking temperature), and other biological signs (e.g., changes in the cervix). A woman records the characteristics of her cervical fluid secretions and monitors the basal body temperature, which rises after ovulation. Couples cross-check these two primary signs and follow specific guidelines to determine the beginning and end of their fertile days. For additional information on the STM, visit:
