For many women who enter menopause naturally, their menstrual cycle first becomes irregular. On average, it stops completely within about 4 years. Other symptoms that can happen during this time include: 1  Mood swings. 2  Lower sex drive. 3  Hot flashes. 4  Sweating. 5  Racing heart. 6  Headaches. 7  Vaginal dryness and soreness. 8  Painful sex. 9  Trouble sleeping.
The duration of menopause is very hard to predict, as each woman's situation is vastly different. Women typically start experiencing hot flashes, mood swings, vaginal dryness and other menopause symptoms when they are going through perimenopause.
