Your Right to Know

NFP International is an organization that teaches all the fertility signs and rules, provides Catholic Church teaching related to the practice of natural family planning, and teaches ecological breastfeeding for the natural spacing of babies. We believe that married couples have a right to decide what options they want to use, not the NFP teacher. The only way you can choose is by knowing the legitimate moral choices.

Listed below are the various NFP-related options that couples have a right to know.
