I was treated for a UTI last week with Macrobid for 5 days. During the 5 days my menstrual period started and ended. I have continued traces of blood in my urine now 3 days after the last day of my period. In addition to the bleeding I have continuous cramping in a muscle on the inner part of my vagina (contraction like pain that often stops me in my tracks). The cramping has been around for years but occurs more often the past few months. It used to "cramp" about 4 times a year, now I "cramp" once a week. Do you have any advice?
