Changes in menstrual cycle
Your period may not be as regular as it used to be. You may bleed heavier or lighter than usual, and occasionally spot. Also, your period may be shorter or longer in duration.
If you do miss your period, make sure to rule out pregnancy. If you’re not pregnant, a missed period could indicate the onset of menopause. If you do begin spotting after not having your period for 12 consecutive months, make sure to talk to your doctor to rule out any serious conditions, such as cancer.
