Are you saying the stoma itself is bleeding? 

Or you actually have blood coming out of the stoma? 

I think your (not sure) your referring to the stoma itself. 

If you are it's normal.   The stoma's capillaries (spell) are right at the surface and bleed super easy.  Even rubbing the inside of the bag or the edges of the wafer rubbing it will have it bleeding. 

I.... During a change... Use q-tips and sometimes even touching it lightly will put a bit (blood) of red on the q-tip.

Now if you are referring to the blood coming "out" of the stoma. That would have to be answered by someone else. I've never had that happen. 

Hope this helps.

Thanks for the input. To be honest im not sure whats bleeding i just see little trickles of blood in the bag after i run. Its already stopped bleeding by the time i check it out.

It probably the stoma itself.  It does stop bleeding quickly. 

Welcome.
