Was too much cartilage added to the bridge of my nose? Or is this extra swelling? How would I fix if the bump stays? (Photo)

I had open rhinoplasty 3 weeks ago to correct a small hump that was on my nose. During the surgery my surgeon thought my bridge looked to low after the bump was removed and then unexpectedly had to build my bridge back up with cartlidge. I'm now seeing a bump on bridge as my swelling has gone down. The bump is hard and my swelling going down just makes it look worse. He said to tape and wait. Did he add too much cartilage? Or is this extra swelling? How would I fix eventually if the bump stays?
