Still leaking...

So I tried pumping for breast milk and unfortunately it did not work. So now I’m about 4 weeks PP and it looks like I’m still leaking a little bit which doesn’t worry me a whole lot- however, I have noticed that it doesn’t smell good and whenever it leaks, it has a bad smell. I am not sure that the smell is normal. Should I be concerned and see my doctor before my 6 week PP check up? My next apt with her is within the next couple weeks. Has this happened to anyone else? Any advice would be great!
