I'm at the doctors again to have everything checked out... They ran a UA and I have blood in my urine, lower back pain along my spine and discomfort in the pelvic region.... As of right now they think it might be a uti but there are other possibilities that if the meds they prescribed don't clear up everything they are going to run more tests in a week
