Two common natural family planning (NFP) methods are the ovulation method based on characteristics of cervical mucus and the symptothermal method based on changes in cervical mucus, basal body temperature, and the cervix. Both methods are effective when used correctly. Nurses should understand the principles of NFP and introduce these methods in discussions of family planning options. Interested clients should be referred to a certified NFP instructor for education and supervision.
