I hit my nose on the door now I have a bump. (photos)

It is hard to say from the very dark photos posted.  If you notice a bump then it might be a good idea to see a plastic surgeon.  Best of luck.

Trauma to the nose can cause a displaced nasal fracture, a nondisplaced nasal fracture, a callus formation along the bridge line, a fracture of the internal portion of the nose known as a deviated nasal septum, and a dislocation of the upper cartilages off of the nasal bones. It's best to seek out a consultation and examination by a double  certified ENT/facial plastic surgeon to document the extent of the injury along x-rays. For more information  and many examples of nasal fracture repair, please see the link and the video below. If the bump is still present after three months, surgery may be needed to remove it. 

The photos are really too dark to see anything, but hopefully what you are experiencing is simply swelling. Wait until 6 weeks after the injury and if the bump is still present then schedule a consultation with a board certified plastic surgeon to have it assessed in person.Kindly,Kouros Azar
