Reoccurring Uti,stomach cramp,

I am woman in my 20.i have experienced uti for almost over a year now.at first,it was just frequent urination and the feeling that my bladder is full almost all time. I was diagnosed with uti at that time,since bacteria and blood could be found in my urine.however, this was a year pass.i recently went to the doc again and they said my urine ph is normal which indicates that there’s no bacteria in my urine. I recently take d mannose for almost 10 days. I noticed less urine but my stomach cramp all the time to the point I can’t even feel is my bladder is full or not. I often had dehydration even when i drink much more water than usual.its hurt when i pee however there’s no burning feelings.both my right and lefts side hurt even when i pooping.its almost as if there’s a limit to the pressure i can use when peeing and pooping. Sometimes,i also feel a sharp pain in my middle right side of my stomach. All this still doesn’t get better except the amount of times i peeing. All the prescribed antibiotics by the 5 doctor i went are all taken accordingly but the pains doesn’t go away. This has affected my life in many ways. I want to know if this will affect my kidney as that is my biggest fear right now or is it symptoms for other sickness?should i went to the doc again?
