Women spend over 7 years (in total) of their lives menstruating.
A woman menstruates for an average of 2,535 days in her lifetime, or almost 7 years out of 39 (5 days per 28-day cycle)!
On average, women get a period for about 40 years of their life. Most women have regular periods until perimenopause, the time when your body begins the change to menopause. Perimenopause, or transition to menopause, may take a few years. During this time, your period may not come regularly. Menopause happens when you have not had a period for 12 months in a row. For most women, this happens between the ages of 45 and 55. The average age of menopause in the United States is 52.
