I am concerned about a pink discharge I am having. I am on the Depo prevera shot and have been for two months now and, I was also on Depo for several years a few years back, I just went back on it. I am treating an infection right now (Vaginosis) with cream for 7 days and last night when I inserted the cream for the first night the tube was pink when I took it out. All day today I am having a pink discharge. Should I be worried? Why am I having a pink discharge?
