Natural Family Planning (NFP) refers to methods used by couples to achieve or avoid pregnancy based on the observation of natural signs of fertility. These signs include changes in a woman's body temperature, cervical mucus, and menstrual cycle patterns. By tracking these indicators, couples can identify fertile and infertile days. NFP is a holistic approach that does not involve hormonal contraceptives or surgical procedures. It promotes awareness of the reproductive cycle and encourages communication between partners. Many couples find NFP aligns with their values, as it respects the natural processes of the body while allowing for family planning.
