Natural Family Planning

What is Natural Family Planning?

Natural Family Planning (NFP) refers to various teaching about the nature of love leading to a more beautiful sex life and a series of methods that help couples achieve, space out, or postpone pregnancy. NFP methods observe the naturally occurring signs of a woman's menstrual cycle fertile and infertile phases.

Unlike contraceptives, which change the character of sex to render it unfruitful, methods of NFP support God's design for your sexual life, where the union between husband and wife is both love-giving and open to life.

"These methods respect the bodies of the spouses, encourage tenderness between them, and favor the education of an authentic freedom" (CCC 2370).


I've been told the NFP methods are not effective

Quite the opposite. When used correctly, NFP has the same range of effectiveness as the most effective artificial means – without the side effects for the sustained use of drugs and the moral dilemmas. The Archdiocese supports four different scientific methods and a network of certified instructors so that you can select the best one for your couple's dynamic and needs.

Sympto-Thermal: The Sympto-Thermal Method identifies a woman's time of fertility through observing cervical mucus, basal body temperature, and cervical changes. Check the Couple to Couple League (CCL) website for additional information.

Billings: Based on over 50 years of ongoing scientific research, the Billings Ovulation Method® is a highly effective yet simple approach. It can work effectively for women whether they are coming off hormonal contraceptives, breastfeeding, weaning, or approaching menopause. Regardless of the particular situation, the four simple rules of the method are the same for everyone. Learn more at BOMA's website. 

Creighton: The Creighton Model (CrM) is a method based on a woman's cervical mucus observations. The technique can be used with the science of Natural Procreative (NaPro) Technology to evaluate and monitor reproductive and gynecological health. Find out more here. 

Marquette: This model uses a fertility monitor to measure reproductive hormones in the urine along with the method's algorithm. The approach is suitable for women with regular cycles, irregular cycles, and breastfeeding, postpartum, or approaching menopause.

Check the website of the Institute for Natural Family Planning at Marquette University for additional details. 


How can we know more?

We encourage you to start by attending an introduction talk to Natural Family Planning:


Family Life Ministry is committed to providing parishes with support and resources to promote Natural Family Planning.
All couples are invited to attend this NFP formation program.

The classes are offered every second Saturday of each month starting on April 10 at 9:00 am in the Cameron Retreat Center at the St. Dominic Chancery.
Each Saturday is composed of two classes: The first one is an Introduction to Natural Family Planning in a broad scope; while the second one focuses on a specific NFP method, such as Symto-thermal, Marquette, Billings, or Creighton, all of them being approved by the Archdiocese. We warmly encourage you to stay and go deeper in the method of your preference!

The cost is of $25 per couple for Introduction to NFP, or $30 for a Specific Method class in addition to the Introduction class. Please press the registration button below to choose the class you would like to attend.
