Everytime I pee urine is cloudy and UTI test came back negative, could it be yeast infection? I have dry skin and hair as well and stomach aches.

Cloudy urine. The usual cause of cloudy urine is phosphate crystals, which are normal. It's the result of fluid intake and diet. It's not harmful. You can test this by adding a few drops of acid (e.g. vinegar) to a urine sample. If phosphate crystals, the urine will turn crystal clear. Yeast infections don't cause cloudy urine, and this has nothing to do with dry skin etc. See doctor if still concerned.
