• What is Natural Family Planning (NFP)?

    NFP is a term for methods of family planning that utilizes knowledge of the body’s naturally occurring signs of fertility. NFP uses no chemicals or devices but rather the avoidance of intercourse during the fertile phase of a menstrual cycle if pregnancy is to be avoided and the intercourse during the fertile phase if pregnancy is to be achieved.

  • Isn’t NFP just guess work?

    No. NFP is based on the biology. The method of family planning that utilizes guess work, is really contraceptives. Couples do get pregnant on contraceptives because when a woman is in the fertile phase of her cycle, she can become pregnant. Couples who use contraceptives guess that their chemical or device will work. On the other hand, couples using NFP know how to identify the fertile phase and use the only 100% guaranteed method of avoiding pregnancy, which is abstinence during the fertile part of the menstrual cycle.

  • Is NFP the same as the Rhythm Method?

    No. Modern methods of NFP are based on daily observance of the signs of fertility and infertility. It does not predicting when ovulation will occur as did “rhythm.”

  • Is NFP going to be a serious inconvenience?
