The Couple to Couple League of Central Indiana works to teach and promote Natural Family Planning (NFP). NFP is a safe, healthy, moral and effective way to plan your family. It is just as effective as contraception in postponing a pregnancy but works with God's design for a woman's fertility instead of circumventing it. NFP can be used to postpone a pregnancy or to become pregnant. It can also be very helpful in diagnosing reproductive problems and can help couples who are suffering from infertility.
