Bleeding that's still flowing normally past four to six weeks after a C-section needs your obstetrician to check for a cause. That's a separate issue from your stool symptoms.
Next Steps
Please book a check-up soon, since an ultrasound can help see what's keeping the bleeding going. For the itching and pain passing stool, ask your doctor to check for a possible tear or hemorrhoids from delivery.
