It is normal for some cysts to bleed if the cysts happens to rupture.
Most cysts are non cancerous and harmless but can be annoying and you can have a doctor remove the cysts if it's bothering you.
Some cysts will eventually go away on their own without treatment but whenever I've had a cysts it was annoying and did bleed some and so I had a doctor remove the cysts surgically.
The cyst was harmless but was just annoying and if it's bleeding it would be a good idea to see a doctor about it just to make sure the cyst you have in not cancerous.
Most cases of cysts are not cancerous even when they bleed but seeing a doctor about it would still be a good idea just to be sure.
