Sorry to bear this message, but if in doubt, don't ride. Pain, unfortunately, often accompanies a fracture. If you need to dull the pain with medication, be extremely sensitive to the potential impact on your reaction speed and balance.
The other thing the pain might signify is that you are doing it more damage by going over the bumps and so on. I agree with John E, if it's still hurting, take some time off and allow it to heal.
