<s>[INST] I'm on Depo my last shot was 7-17-13 and I have been on it regularly for about 4 years.  Today I have experienced moderate to sever lower abdomen cramping, back pain, and brownish spotting.  I have seen one bright red small clot.  I miscarried 12-15-13 at 9 weeks.  this pain is similar but I haven't had the bright red blood.  I took a pregnancy test around the beginning to middle of August.  Results were negative.  What could this be? [/INST] Hello. Thanks for writing to us. The symptoms that you are having are normal in case of a depo injection. The mild brownish spotting spotting usually subsides on its own in few weeks. Please do not worry.I hope this information has been both informative and helpful for you.
