whether she wants to go or not is irrelevant. she needs to go because she is having signs of a urinary tract infection perhaps one that is involving the kidney like a pyleonephritis. she could also be passing a kidney stone. either one of these could be serious so waiting is not a logical option. as you know it is not normal to pee blood (hematuria). since the kidneys are located high in the back it would be in her best interest to seek medical care so she can be properly diagnosed and treated. it may be up to use to convince here.
my girlfriend is peeing blood and has back pains. she doesnt want to go to the doctor yet. any help. please
