I have been having recurrent UTI for past 7 months I had one recently usually symptoms so I have taking cranberry pills plently of water usually have antibiotics but this symptoms gone without taking antibiotics can tjat happen?

Yes. Many bladder infections can be self-limiting, ie will resolve with time and the protection by your own immune system. Dilution and flushing with increased fluid intake and the possibility of a bacteriostatic effect by cranberry concentrate can often resolve and infection.
