Bump in mouth
I have a small pimple-sized bump inside my right cheek. It is soft and appears to be dark red or brown in color and may be filled with blood. It is not sore.
Sounds like you may have bitten the inside of your cheek. The formal name for this is petechial hemorrhage. A common term is a blood blister (a very small one). It should disappear without any treatment over the next 7-10 days.
