I agree that you really should be seen by a doctor or nurse practioner ASAP - a week is far too long, and by that time the problem could be far worse than had it been treated promptly! If you have an UTI or kidney infection the sooner it is treated the better - for example, if it is only an UTI now, it could spread to your kidneys if you delay treatment.
I have had two UTIs in the past month (yuck), with symptoms very similar to what you described (but no green pee), and was able to call the clinic this morning and get an appointment for the afternoon. The doctor had me give a urine sample, quickly confirmed that I had an infection, and gave me a prescription for antibiotics. (She will also do a culture, which will take longer, to make sure the bacteria will respond to the antibiotics.) I think most doctors and nurses agree that a UTI is not a life threatening emergency, but it is definitely something that should be treated promptly.
I would recommend calling the doctor's office again (or email, if he/she has that), as well as searching for other clinics. You might even try calling the local hospital - sometimes they have patient advocates, and they might be able to recommend a clinic. If you want to PM me the town you are in I can try searching too.
As a side note, I saw that you are located in GA - I am there too, and was able to get my antibiotics for free from the Publix supermarket pharmacy. (I am not affiliated with it or anything, and when I asked the pharmacist why they were free, he said it is so they can compete with the other stores offering $4 prescriptions.)
