Does an ear bleed if the eardrum isn't ruptured?

Yesterday, my 3 year old son woke up screaming and crying. I finally got him calmed down, but he would start screaming if I touched his ear and I saw some puss in it, so I took him to the ER. When we got there, I saw a bit of blood. They had to clean his ear with peroxide to see inside it and he does have an ear infection, but they said they didn't see a perforation. They gave him antibiotics. I just noticed more blood in his ear and I'm worried. Is it possible that his eardrum ruptured? That happened to him once before, but then he had a lot of blood and it was running out of his ear. This time there's just a little bit of blood inside the ear.
