Depo shot bleeding

ive had my “period” for nearly 4 weeks now. On and off. Heavy, and light. now let me tell you ITS ANNOYING!!!!! Can someone please tell me how to get rid off this! I got my first every form of BC (Depo shot) in my entire life on  Aug 6th and im getting my second one Oct 30th. Anywho, i hate this. I really do. It interferes with so many things! i just want off of this shot but my mom doesnt want me too.
