Just to clarify, you are not yet in menopause, correct? To be in menopause, you have to have not had a period for 24 months. You may be peri-menopausal if you are starting to have irregular or skipped periods, but your physician would need to confirm this. Many women have painful periods (cramping, etc.) during their peri-menopausal time, and may find that the few periods they do have are very heavy. What is your sensory level? The uterus is innervated at T10. You mentioned you were late for your period. Did it start yet?
