UTI. Meds didn't work!

Okay, so I did go to the doctor 3 days after I got uti. It is not the first time in my life, that's why I already knew the feeling (symptoms). Since I was on pain relief meds the time I went to the doctor I didn't have to take a pee test. The doctor trusted me on my words and the way I explained the problem, I guess. I got prescripted with some antibiotics which I had to take for 7 days twice a day. Everything was ok, I stopped feeling the paint after a third day. BUT!!! Today is the first day since I stopped (got done with my meds) and everything is back to the way it was before I started the course. What do I do!??? I don't want no more antibiotics cuz of their affect on the body. Help!
