As Pope Francis writes in Amoris Laetitia, our sexuality “is a gift from God that enriches the relationship of the spouses. As a passion sublimated by a love respectful of the dignity of the other, it becomes a ‘pure, unadulterated affirmation’ revealing the marvels of which the human heart is capable. (AL, 152) In other words, as a gift of married love, the conjugal act is a symbolic reflection of the inner form of love, which is a vow. “I love you,” means I love you completely and forever.
Whatever God’s plan for a married couple, true love is always fruitful and life-giving. As married couples renew their vows through the conjugal act, they are called to responsible openness towards co-creating new life with God. Family planning decisions are prayerfully made through mutual discernment, enlightened by faith. This is where “Natural Family Planning” comes in.


What is Natural Family Planning (NFP) a.k.a. Fertility Awareness-Based Methods (FABM) of Family Planning?
Natural Family Planning (NFP), or Fertility Awareness Based Methods (FABM) of Family Planning, is the umbrella term for the natural, healthy, morally acceptable methods of family planning recommended by the Catholic Church to help couples space, achieve, or avoid pregnancy. It helps married couples either achieve or postpone pregnancies, while respecting the love-giving (unitive) and life-giving (procreative) nature of the sexual act. NFP enriches a couple’s relationship while encouraging a level of intimacy that reflects marital love: one that is free, total, faithful, and fruitful. Furthermore, NFP is completely natural, “green”, and “organic”– no drugs, devices, or surgical procedures are used to avoid or achieve pregnancy.
During each monthly cycle, a woman normally becomes fertile and then infertile, with her body providing natural signs to indicate where she is in her cycle. Scientifically and medically researched methods of fertility awareness teach couples how to observe and interpret these signs, enabling them to achieve or avoid pregnancy naturally. When couples learn about NFP, almost all will, at the very least, come to a greater appreciation for the wonderful gift of their fertility, their sexuality, and how their bodies were made.

NFP Methods and Providers
Billings Ovulation Method
The Billings Method is one of the original methods and relies on just one sign of fertility—cervical mucus. It works well for women with regular cycles and has as relatively low ongoing cost. For more information about the Billings Method, visit boma-usa.org or call 651-699-8139. Find a Billings instructor here.
Creighton Model FertilityCare System
The Creighton Model is a scientifically proved method that required couples to observe and record certain biomarkers. Using these biomarkers, certified FertilityCare practitioners assist each couple in determining when they are fertile as well as identifying possible health concern, and follow-up as needed. Works well for women in regular or irregular cycles and women with reproductive concerns that can help identify root causes and offer treatments. For more information, visit fertilitycare.org or contact Orchid FertilityCare in Escondido, CA.
Sympto-Thermal Method
The Sympto-Thermal Method is a relatively inexpensive method that charts multiple signs of fertility, mainly cervical mucus and basal body temperature. Cost-effective and can be used for both regular and irregular cycles, however women with irregular sleep schedules may find it challenging. Couple-to-Couple League (CCL) and SymptoPro are two organizations that specialize in teaching and promoting the Sympto-Thermal Method. Certified teacher couples are available in-person or online. To connect with a local CCL couple, contact the Office for Family Life & Spirituality (858-490-8256) or visit https://ccli.org/learn-nfp-from-ccl/.
Sympto-Hormonal Methods
In addition to the traditional biomarkers of cervical mucus and basal body temperature, Sympto-Hormonal Methods track hormone levels with fertility monitors to assess when a woman is fertile. The fertility monitor readings provide a high degree of objectiveness, although it is not the most cost-effective method. The best known Sympto-Hormonal Method is the Marquette Method. Click here to learn more about Marquette or visit marquettemethod.com to find an instructor. Boston Cross Check is another Sympto-Hormonal Method that meets the USCCB’s standards for diocesan NFP ministry. Visit bostoncrosscheck.com to learn more and find an online instructor. FEMM Health is another great resource for fertility awareness with a special emphasis on hormonal health, with multiple San Diego-based instructors.

Parish NFP Ministry
What would a parish NFP ministry look like? Here are some suggestions:
- A parish NFP ministry leader doesn’t necessarily need to be an instructor, but they should have an understanding of the NFP landscape with the pastoral skills to respond to needs with compassion and sensitivity.
- Get trained as an NFP Ministry Leader (a.k.a. NFP Ambassador!)
- Start a support group for women practicing NFP.
- Work with youth & young adult ministry to provide fertility awareness education to teens and young adults.
- Provide a contact in the bulletin/website for people to contact with questions they may have.
- Be a source of knowledge about NFP for parish leaders.
- Prepare information about NFP that can be included in bulletin, Flocknotes, or social media.
- Stay current by remaining in contact with diocesan and USCCB leadership.
- Distribute pamphlets and flyers that provide basic information about NFP.
