UTI? blood in urine?

so the other day i was sure i had a UTI because my urine smelled and it hurt to pee a little. and then it started hurting in my abdomen area so i bought some dried cranberries because i thought it'd help. ate some and then later that day my pee was kinda pink/red-ish. i'm not sure if it's from the cranberries or if it's just a UTI but i'm getting a little worried please help!!
