I recently went off the depo provera shot after 1 dose. I was diagnosed with PCOS last October. Since stopping the shot, I still havent had a period. Ive been really tired, sleeping alot, have headaches, back pain, and joint pain, mainly in my legs. I also have frequent urination, and have been having some lower abdominal pain. I thought I might have another cyst, but that deosnt explain the joint pain.
