"i&#039;ve been on depo for two years. 1st year was rocky with the spotting and mood swings. 2nd year was great. still not pregnant, no more side effects. i take my vitamin c and d. i&#039;ve gained 3-5lbs, no difference. i&#039;ve tried the pill and patch and hated them equally for different reason. i would hate to have to switch birth control. i love 4 shots and no babies. its great for me. good luck with your experience."
