abnormal uterine bleeding
"One month after injection date I am experiencing the most painful period ever.  I can't leave the bathroom for fear I will bleed threw everything.  I am changing my tampon ever hour (or less).  I have been taking muscle relaxers to try and ease my pain,  but they don't do much.  
I have never had a menstrual cycle  like this. Usually the first day is heavy but then isn't so bad.  On the depo  shot I have been bleeding for several days.  I am making an appointment with another gynecologist on Monday to see if there is anything I can do.  
I am so upset that the doctor didn't warn me about the side effects before giving this to me.  
There is also acne, weight gain and sever cramps (with out my period)  that I had to deal with the first month"
