Hi I m on the depo provera shot and I have been on cipro for a kidney infection and just a little while ago I went to the bathroom and when I wiped and on the pad I was wearing had liquid brown vaginal discharge on it. I have had kidney stones before and I have still had the pain in my abdomen and back only on the right side and I m worried what it could be. I had the kidney stones in may of last year and had them removed. Could I have a stone or is the infection getting worse.
