50sThe average age of menopause (the point at which you’ve had no periods for one year) is 51, which means that many women are still menstruating well into their 50s-and many women stop well before their 50th birthday.

If you’re in your 50s and you’ve gone a year with no periods but then start bleeding, you may want to talk to your health professional. Because a rogue period could indicate cancer of the endometrium, it is important to figure out if it’s normal or not. 10 percent of post-menopausal women in their 50s, and 20 percent of post-menopausal women in their 40s, will have a rogue period after having none for more than a year.

Pay attention to how you felt before the flow-if you had bloating, sore breasts, mood swings or other symptoms, the bleeding is probably normal.

Other causes of vaginal bleeding at this stage include atrophic vaginitis (dryness and thinning of vaginal tissue) and endometrial hyperplasia (overproduction of cells in the uterine lining). But it’s probably your ovaries making a diva comeback, and that’s not unusual at all. Check with your doctor, just to be sure.
