Natural Family Planning (NFP) is based on a woman's awareness of when she is fertile (likely to become pregnant). By learning how to tell when you're fertile, you can know when to avoid sex. This can help prevent pregnancy. To learn NFP, it is advised that you take a class or work with a qualified teacher.
Talk to your healthcare provider about the effectiveness of this birth control method.
A woman is fertile only during a certain part of her monthly cycle — just before and during ovulation. By learning when you ovulate, you can know when you're likely to be fertile. You estimate when you're ovulating by observing and keeping track of certain physical signs. You can then avoid sex or use a barrier method during that fertile time. But be aware that each woman's cycle and signs are different, and no woman's cycle is perfectly regular.
