What is natural family planning?
Natural family planning is a general name for the methods of family planning that are based on a woman’s menstrual cycle. A man is fertile throughout his life, while a woman is fertile for only a few days each cycle during the child-bearing years. Some believe that NFP involves using a calendar to predict the fertile time. That is not what NFP is today. A woman experiences clear, observable signs indicating when she is fertile and when she is infertile. Learning to observe and understand these signs is at the heart of education in natural family planning.
When a couple decides to postpone pregnancy, NFP can be very effective. NFP can also be very helpful for couples who desire to have a child because it identifies the time of ovulation. It is used by many fertility specialists for this purpose. Thus a couple can have marital relations at a time when they know that conception is most likely to take place.
