For the past couple of weeks i've had bad smelling urine. It's cloudy and its colour is a dark yellow most of the time. It seems to me like a uti but it also caused a bad smell in my vaginal discharge which I believe could just be because of the bad smell period but i've also noticed at times an intense fishy smell. I'm not in pain at any time and there have been no bleedings occuring. I had a urine culture done about 6 weeks ago and they didn't find anything unusual. What could this be?
