Does having cloudy urine mean that i'm hiv positive?

Not specificly: It means you have extra material in your pee or very concentrated pee. It might be a urinary tract infection, blood from an irritated urinary tract or protein spilling from the urinary tract. You might have HIV but i would this would not be where i look for that answer.

No: Clouded urine can occur simply from precipitation of salts in the urine as they hit the toilet water, or there can be infection, or other explanations. If you think you may have been exposed to hiv, strongly suggest you be tested asap. And in the future practice safe sex.
