I feel like my menstrual flow is actually deteriorating. can this happen with age?

Perimenopause: Your question is not clear but you are in near perimenopause age that is between 45 to 55 and average menopause about 50 and it is common you will have irregular periods or escape period sometimes light or rarely heavy periods. Do monthly period diary for three months if not regular it will be wise to see your Gyn or F/d to give you guidance then Good luck

Menopause?: Menstruation stops in most women below age of 50 but there are variations 47 appears to the average Have a check up with a gynaecologist
