We've already discussed the risk of a brain bleed. Stop researching. It will only drive you nuts. It sounds like you are doing fine and recovering like a normal concussion. It can take a few more weeks to finish recovering.

A subdural hematoma would cause a VERY painful headache, likely constant nausea and vomiting, loss of motor control (stumbling) and more.

You have a mild concussion. That is all. Slow down, Reduce stress in your life and you will recover faster.
