As women get older, their periods can begin to change. This perimenopausal time typically starts when a woman is in her 40s and lasts about four years. (The average age of menopause, when periods stop, is 51.) For some women, the transition means unpredictable, prolonged or heavy bleeding, and that can be frightening. Now new research shows that these changes may be quite normal.
