Bleeding accompanied with a terrible stench?

Dr., I would like to clarify a doubt, I took the contraceptive injection, after 2 months and 10 days a bleeding started, so that's fine, because as soon as it started I did a search for the internet and realized that it is "normal" but if it was only the bleeding would be good, but this bleeding came with a terrible smell, smell rotten or something, I know that you can not give me a concrete answer because I can not examine myself, I just ask to know if it could be possible that the injection caused an odor, I have not been to the doctor because I'm traveling with my boyfriend and I'm going back to Brazil in a few weeks. Could Dr help me for now? Since now, grateful!
Expert answer:

Bleeding or discharge with an unpleasant odor usually indicates some type of infection, you need to see a doctor.
