"my first shot of depo was great, no mood swings or any other side affects other than some very light spotting. happy with my first shot, i got a 2nd but it didn&#039;t turn out as the first shot did. i&#039;m happy because there&#039;s no mood swings or really any mental side effects which is why i switched from the pill. however, i was told my period would completely go away or just be light spotting, but for some reason i have now been having a normal/heavy period for over a month now which concerning. i&#039;ve also been experiencing a lot of headaches, and cramps that can get so bad they&#039;ll sometimes wake me up from dead sleep. i&#039;ll be going to the doctor soon to get off of this, blood loss is not fun :c don&#039;t think this is super common though"
