So I started the Depo shot in January and recently stopped using it due to 6 months none stop bleeding. I now have been off the shot for a month and I have really bad paines in my uterus, ovaries, cervix, well in that whole area. There is also this little lump in my ovaries.And I'm feeling like I have the flu. My bones, mucles and head hurts... is it semptoms of comeing off the shot or is this serious?
