A menstrual cycle normally lasts from 21 to 35 days, although teens and women in their forties may have longer, irregular cycles up to 45 days. If you are nearing menopause, you can expect that the time between your periods will probably get longer and eventually stop. Other signs of approaching menopause are hot flashes and mood changes.
A normal period usually lasts about three to five days; anything longer than seven days is considered prolonged bleeding.
If you are you are not approaching menopause and your period becomes irregular, it could be a sign of stress, dramatic weight loss, or conversely, sudden weight gain. All these conditions can affect your body's hormone levels and may cause changes in the length of your cycle. Medications such as antidepressants also can be a common, harmless cause of cycle changes. Certain endocrine conditions such as polycystic ovaries and thyroid disorders also can cause irregular cycles; visit a specialist regarding these disorders.
