Hi, A Week Ago I Had A Bladder Infection With

Hi, a week ago I had a bladder infection with blood in my urine, bet after a course of antibiotics I am feeling well so far. However, from yesterday I have noticed small white particles flouting in my urine. I have no pain around bladder area, no temperature and generally feeling well. Apart light pain at the bottom of my back. But I do have back problems, so I dont know whether its related to my urine particles. Also, after bladder infection I have been drinking much more water, and I mean a lot of water, like tea, water, also been eating juicy fruits such as watermeleon. I dont know, if all the liquids now are just cleaning out my bladder, but those particles are really scaring me. Please Tell me what could that be. I am awaiting an appointment to GP, but I only noticed particles yesterday. Thank You, Kristina
