I doubt that the doctor can do anything for it, but it might not be a bad idea to see one to prevent infection and to see how bad it really is. If you ruptured it very badly, they can put a sort of patch on the eardrum to help it heal. When mine ruptured due to an ear infection the hole was so small they couldn't even see it, so they just told me to keep water out of it (plug it up with something when you take a shower) and it healed on its own. You didn't say how much blood there was. It could just be that you scraped the inside of the ear canal and that is where the blood came from. Any changes in hearing? If you are having difficulty hearing out of that ear, definitely go to a doc and get it checked. The monetary aspect is understandable, but consider whether you want to live with hearing loss or not. Good luck.
Bleeding in you ear could be dangerous. You could have ruptured your eardrum, popped blood vessels or something else, and if you don't get it checked out, that could possibly lead to hearing loss. You do know that when you clean your ears, you are not supposed to shove your Qtip down the ear canal. That is not the correct way to clean your ears. You can damage your ear that way. Good luck, and get that ear checked out.
