About 4 days ago i had this pimple looking bubble on my gums, i left it sit and waited for it to go away but 4 days later that same bubble turned into a small hole and this morning i was brushing and it was bleeding and i was concerned about it?

You should very well be concerned. You appear to have a draining abscess with a fistula based on your description. Without an exam and radiographs it is impossible to diagnose your problem. Your local dentist can examine you and determine if you need further treatment.

Time to see your Dentist. Although there are other possibilities, most probable cause is a draining abscessed tooth. The cause of the infection must be determined and treated with alacrity.
