Help with Urinary Tract Infection?

I have a urinary tract infection. What are some natural home/store remedies to help? I do not have money to go to doctor and medical insurance has ran up. So far I have been staying hydrated with lots of water and about 3-4 cups of green tea a day and it has helped tremendously. I got a bottle of cranberry juice but after that I switched to the 1 a day cranberry pills. What else could I do? I do not want to over react but I am do have the concern of it turning into something serious?
