Results of Urine Analysis

The results came back but the urine specimen I gave them on Wednesday was contaminated so I do not know for sure if I have an UTI exactly. I am on an antibiotic that was prescribed to me on Thursday, and I was told to continue the antibiotic and have a specimen done in several days. I just do not know what to do, except go to the ER or urgent care, and redo everything for my family doctor here in town and get prescribed something for it if I do have a true UTI. I have never had a contaminated urine analysis before so this is all new to me. This weekend has not been the greatest weekends for me. I am baffled, confused, and a little annoyed about all this. AARRGG!!
