First, CALM DOWN AND TAKE A DEEP BREATH! And, even IF it is cancer, two weeks won't matter. Two months would.
An infection could explain all your symptoms; usually bladder cancer does not manifest itself as an infection. You are doing absolutely the right thing in making an appointment with a urologist. They are the ones to help you with a treatment-resistant infection.
Don't worry about anything else right now....it is premature. Once you have seen the urologist and have a definitive diagnosis, you will know what to worry about
Best of luck to you.
