I have been on Depo Provera for about 7 yrs with the only symptom being a propensity to gain weight. Now I have taken myself off of it and am experiencing all of the classic symptoms of menopause with a vengeance! I am only 40 yrs old and am not sure whether I have just messed my system up or if the Depo usage precipitated the start of menopause. Has anyone ever had this experience?
