Puttypoo - blood in urine, now on 2 week pathway. So scared

Had blood and clots in my urine.  GP gave me antibiotics and it cleared up, most urine clear now but sometimes a bit cloudy.  Just had a call from aGP to say there was no infection and I have to see a neurologist on the two weeks pathway.  In my mind I already have cancer and am scared out of my wit's.  Everything I have read says that if you are passing blood with clots then it's too late.  HELP
