Natural Family Planning

Choose a Method and Register

Natural Family Planning (NFP) is an umbrella term to describe the methods used to achieve or avoid pregnancy based on observation of the naturally occurring signs and symptoms of the fertile and infertile phases of a woman’s menstrual cycle. Couples may use methods to avoid pregnancy by abstaining from sexual intercourse and genital contact during the fertile phase of the woman’s cycle. No drugs, devices or surgical procedures are used to avoid pregnancy. The methods of NFP reflect the dignity of the human person within the context of marriage and family life and promote openness to life and the value of the child. By complementing the love-giving and life-giving nature of marriage, NFP can enrich the bond between husband and wife. (Standards for Diocesan NFP Ministry, 2010Parenting Resources | One More Soul

1. Sympto-Thermal Method (STM)

Sympto-thermal methods are multi-indexed methods of NFP. A woman is taught to observe her multiple signs of fertility. STM methods teach a woman to observe her primary signs of fertility (cervical mucus, basal body temperature and cervical changes). The secondary signs of fertility (breast tenderness, back pain, etc.) are also taught. Among STM providers, variations exist in some rules, charting two or more of the primary signs of fertility, as well as differences in chart symbols. Despite the variations, all refer to the multi-indexed methods as “STM.” The following options are available:

You may register online for a class live and onsite (classroom setting held locally), live and online (virtual classroom) or self-paced and online (online classroom with guidance from teaching couple).

2. Ovulation Method (OM)

Approximately at the time of a woman’s ovulation, a type of mucus is secreted by the cervix. This primary sign of fertility indicates when a woman is potentially fertile. The woman’s correct observation of her cervical mucus is the basis of all cervical mucus methods (CMM). The term “Ovulation Method” or “OM" has become an umbrella term for most cervical mucus methods.
