Hello dear, I understand your concern. In my opinion the White pieces in urine might be due to vaginal discharge or any infection in urine. I suggest you to get complete urine examination done to rule out the urinary tract infection (UTI) and physical examination done to check for any vaginal examination. Increased frequency of urination can be due to pregnancy because of the pressure of heavy uterus over the urinary bladder. But at the same time ruling out UTI is always helpful. Nothing to worry. Take adequate fluids upto 3 litres per day to prevent UTI. In the presence of infection with adequate treatment it will subside. Hope this helps. Best regards.....Dr.Srilatha
