What Causes Painful Urination And Delayed Period After Unprotected Sex?

I recently had unprotected sex, but the guy I was with pulled out before he came (I know it was an irresponsible and stupid thing to do). Now I suspect I may have an UTI because it sort of burns when I pee and the pee itself has an odd smell and looks sort of cloudy (if that makes any sense). And my stomach feels sort of weird. Also my period doesn t come until two weeks but is there still chance of getting pregnant?
