Hi, Pink or brown vaginal discharge with a bad odor could be a sign of an infection. It is possible that the use of vaginal cleansers and condoms with spermicide could have disrupted the natural pH balance of your vagina, making it easier for bacteria or yeast to grow and cause an infection. It is recommended that you see a healthcare provider to get a proper diagnosis and treatment. Your provider may recommend a swab test to check for bacterial vaginosis, yeast infection, or other types of infections. In the meantime, it is best to avoid vaginal cleansers and perfumes, and use only mild soap and water for cleaning the area. Avoid wearing tight-fitting clothing and underwear made of synthetic materials. Take care. Hope I have answered your question. Let me know if I can assist you further.
