Hello I had gotten one depo provera shot about 3 years ago. About 2 weeks ago, I started spotting and then bleeding and then would spot again. Recently , about a few days ago, I have stopped spotting and now have a salmon color discharge with an odor. It's not a fishy smell, but its strong and no matte what soaps I use or how often, it still comes back within a few hours. What should I do? What could this be?
