Natural Family Planning - Choice of Methods

Married love differs from any other love in the world. By its nature, the love of husband and wife is so complete, so ordered to a lifetime of communion with God and each other, that it is open to creating a new human being they will love and care for together.

As a requirement of the Marriage Preparation process at Saint William, all couples must attend a full Natural Family Planning (NFP) course (not the Intro class). NFP is a way of following God’s plan for achieving and/or avoiding pregnancy. It consists of ways to achieve or to avoid pregnancy for a just reason using the physical means that God has built into human nature.

After attending the Marriage Retreat, choose one of the methods below that you would like to learn and follow the link to register. Upon completion of your full course, please provide a certificate of completion to the Marriage Ministry Office. A full NFP course may be taken at any location, online, or as a home-study course.

(Please note: The fees associated with NFP courses are separate from the Marriage Preparation fee of $300.)


Sympto-Thermal Method - Enroll in face-to-face and self-paced online courses at   3 classes, once a month, for 3 months. Please plan ahead.

The Sympto-Thermal Method is based on three key signs of fertility: cervical mucus, waking body temperature and changes in the cervix. By observing and recording these signs each day and applying a few simple rules, you and your spouse will be able to identify your fertility status each cycle. You can then use this knowledge of your fertility status to avoid or try to achieve pregnancy. These signs are easily noticed by any woman who has learned to watch for them and it takes only a minute or two each day to record the signs in CCL’s mobile app, CycleProGo, or on a paper chart. Couples learning the Sympto-Thermal Method are taught by a certified instructor couple and receive the Student Guide and access to online reference tools.


Billings Ovulation Method- 3 classes in a 6wk time period. Please plan ahead. Go to:

Christine Mesich (St. William instructor)

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 pregnancy.


Creighton Model Ovulation Method – Taught individually with a teacher over 8 sessions; meetings every 2 weeks for 2 months, and the rest spaced out over a year. Register at  

Please plan ahead.he CrMS teaches women to observe certain biological signs to monitor their own gynecological health, and to identify times of fertility and infertility. These biological signs include cervical mucus and bleeding patterns, and can be observed and analyzed in all types of menstrual cycles. These signs are charted daily to give a picture of the woman's individual      cycle. Doctors can use the fertility charts which couples are taught to keep as the basis for further investigations if needed.
