Hi, I am 17 years old and have been on the depo shot for a month and a half. I have had no periods since, just some minimal spotting. It's two weeks after my period should have been and I am having a lot of foul smelling, brown discharge and some light spotting. It has been going on for 7 days and continues to get heavier and heavier. I have some pain in my lower abdomen. Should I be concerned? Is this normal? I have had many breast cysts because of abnormal hormone levels, would this maybe have something to do with it?
