Are you swollen at all? When you said your doctor thinks you are pregnant is it because you have gained weight? When I was diagnosed with my kidney problem I swelled up and gained 70 pounds. People were asking me if I was having twins.
The protein in your urine - how did they check it? Did you have a 24 hour urine test done? That is where you take a bottle home and collect all of your urine for 24 hours. That would be the best way to check it if you have not had this done yet.
I would wait to see what the tests say and what the urologist says. If you do not find your answers and still feel bad don't give up! Maybe something else is going on but you really know your body and know when something is wrong. Best of luck!

Did your doctor also order a GFR blood test? I hope you can get a kidney ultrasound. Also, have you been checked for a fissure or hemorrhoids regarding the painful defecation (b.m.s)? Have you had a head cat scan for your headaches?
