Blood on toilet paper 3 months after total hysterectomy urine and lab tests done today pelvic exam all normal what can it be >90 gfr bilirubin of 0.3 ?

Blood on TP: It’s pretty odd to have bleeding 12 weeks out from a hysterectomy. If your pelvic exam was normal then I think you can assume your Hyst is not the cause. More likely would be rectal bleeding (usually from an internal hemorrhoid). As your 51 you should be due for your screening colonoscopy so make an appointment with a Gastroenterologist and you may find some answers there.
