I was on the Depo Provera shot for about a year and I recently got off of it. During the last trimester I was on it, I did not get my period at all. Since I've been off of it I have been spotting constantly and recently the bleeding has gotten really heavy. Since the heavy bleeding, I've been experiencing cramps and lost of appetite. Is this a normal side effect from getting off of the birth control? What else could cause this cotinuous bleeding?
