Hello and welcome... I'm sorry you have had such a tough go of things and are still experiencing pain.
I would venture a guess that most people experience blood in the urine prior to their diagnosis of bc, but as with everything, there are no absolute rules so I would say it is possible to have it without blood in your urine. I really didn't have any to speak of except a little bit on the toilet tissue a few times, but nothing that could be seen in my urine. But that certainly doesn't mean that you have it.
The only way to really know is to make an appointment with a urologist. He/she can do a lab workup which can detect any atypical cells. The definitive answer would be to have a cystocopy which allows them to see inside your bladder with a camera. If you are still experiencing abominable pain, either a pelvic MRI or CT scan would show if there is anything external to the bladder that is problematic. I know they said 2 months and "maybe" an MRI, but that seems to be a long time to be in pain with no answers.
I hope you find relief from your pain soon. Again, welcome.
