Sore in my mouth not sure what it is?

I have these 2 bumps that have the appearance of a canker sore but their not where they usually are. They are right where the inside of my cheek and gum connect. They look like pimples. I know nobody who has . I'm only 15 and don't fool around often. I'm worried though that maybe, somehow it could be. Any help? Should I wait a few days to see if it goes away?
