I am 43yrs. Old and for the last year have noticed that my menstrual cycle is getting closer together. When I think I should be ovulating I will spot for a couple of days, have heavy flow for a day then spot again. Then my next cycle will start 21-25 days later. My cycle is always irregular now. I am having other changes that are possibly signs of menopause. These changes have been slowly coming about for the last 5 yrs. Night sweats, hot flashes during the day, dryness all the time and painful sex, hair texture has changed also. Is this change in my cycle to be expected or should it be something to be concerned about?
