Hard to tell without examination. If there is a bump, it most likely a displaced cartel, and or bone.You will have to wait several weeks at this point to allow swelling to decrease and for potential surgery to re-align the structures that may be damaged.
It is very difficult to tell at this point. The nose gets very swollen when it is injured and just from your description, no one would be able to give you a 'yes or no' answer. I would recommend visiting with a local rhinoplasty surgeon so they can assess in person. Best of luck
