I am 53 years old, and my period is 5 days late. how likely is it that i am pregnant? or is there something else that could be causing this?

At age 53: The chances of pregnancy are getting quite low. Peri menopause can cause menstrual irregularity. I would recommend a home pregnancy test, however. As we age, pregnancy is much harder to maintain, since our eggs are not as healthy. "when in doubt, check it out!" be well.

Menopause: In the months or years leading up to menopause (perimenopause), you might experience these signs and symptoms:irregular periods, vaginal dryness, hot flashes, night sweats, sleep problems, mood changes, weight gain and slowed metabolism, thinning hair and dry skin, loss of breast fullness.Starting at perimenopause, schedule regular visits with your doctor for preventive health care and any medical concerns.
