I am a 40 year old woman that had my tubes tied in Feb. and then had a month long period. Since the end of March now I havent had a period at all. My breast do hurt off and on but know other s/s. After my c-section 17 years ago I did have to take Provera to start my ovulation and periods again. Could I be going thru menopause or just need Provera again to get it kicked in again?
