Increased Understanding of Body & Fertility
By learning to recognize and chart her monthly cycles, a woman gains an increased understanding to her fertility. She learns about the signs her body shows her that she is about to become fertile and when she is no longer so. Since stress, illness, breastfeeding, oncoming menopause, etc. can cause changes to the menstrual cycle, a woman who practices NFP does not have to worry about checking the calendar. She knows when she is fertile by simply observing the changes in her body. By sharing this information with her partner, both gain an understanding of fertility.
