Mama, I need you to check with your pediatrician or go to your baby's checkup soon, bleeding every time you clean it is something the doctor should see, okay? A few of us mums noticed our babies' cords were a bit sensitive too, but the healthcare provider should guide you on the right way to care for it and what's truly normal versus what needs attention. Don't worry, it's likely something small, pero better safe talaga with newborn stuff. Let me know what the doctor says!
