Hi, I had some symptoms for a UTI starting yesterday, including cloudy urine, burning when going, and needing to go more often. It was Saturday and hard to see a doctor so I just drank fluids and cranberry juice. Today is Sunday but my symptoms have gotten worse. Within the last hour I developed abdominal pain, chills, and nausea. Is this something that I should wait until tomorrow to see my doctor or should I go to the ER?
