My doctor has told me of the few symptoms of the depo shot but I was wondering what are some symptoms that you ladies have experienced. I right now am experiencing terrible cramps and tiredness, I'm bleeding alittle bit. Yesterday my spotting was light and brown and today this morning it was a bit heavy and red. 
So what is normal for you ladies while you were on or are on the shot ???
