found out I have a uti and I wasn't told because I peed before in the cup right before I left the doc office. I called in this morning saying I have a burning sensation when I pee and they say BC I have a uti and I have antibiotics waiting for me at my pharmacy . I was so irritated about that because it could've gotten treated already and she didn't even call to notify me.
