Sickness

Okay im a little worried because Wednesday of last week i started peeing alot. Like having the urge to pee which is usually a sign of a uti right? Friday i started to get sick. A fever of 100 degrees, chills, sweating, body aches & the left side of my back kind of hurts with i breath or lay a certain way. I still have a appetite im not nauseous or anything. But i do get weak. I been drinking cranberry juice taking cranberry pills & drink alot of water. Can someone tell me what this could be & if i should go to the hospital ASAP?
