I am 48 years old with a period that is about 10 days late. i have always been very regular, every 4 weeks until recently. My hormone levels have been checked last month with no sign of menopause, I need to urinate more frequently than usual, have headaches, lower back pain like usually during my period. My breasts and nipples are itchy and sore. I do not think I am pregnant as I am not having any symptons other than the urination.
