You could have overactive bladder. You should see your doctor and ask him/her to refer a urologist to have exam and tests.
I think it is less likely that is due to a bladder infection. It could be due to hydrochlorothiazide (HCTZ).
It would cause the clear urine. It makes you urinate constantly. You should see your doctor to have a urine test at first although the infection is less likely. If there is no infection, you should see a urologist to check the urine volume in the bladder after urination to see if there is urine more than normal in the bladder or not. Depending on the result, the doctor will do further tests such as checking the bladder function.
