Possible Uti during labor

Anyone? I'm starting inducing tomorrow evening and for about the past 24 hours I've had burning while peeing. I'm not sure if it's a uti as I had this issue a few weeks back and doc said it was just pressure on my bladder (urine was neg.). I do have an appt. Today for an nst but it's not typically the place where you would bring that kind of thing up. I can make a point to have the nurse call my doctor if need be although the place I'll be today doesn't even have a lab to test pee. Or would it be ok to wait until I'm already at the hospital tomorrow to say something and let them test pee. Anyone?
