My nose was bumped 2 months after rhinoplasty, on the bridge of the nose. Would there be damage done?

Dear laratuna,based on your description, there is a small chance that there is any permanent damage. However, to be sure you should be examined by your plastic surgeon.Daniel Barrett, MD, MHA, MS

From the description you have provided of a SOFT hit, I would not anticipate having any damage.  Any HARD hit to the nose may disrupt the structure early on, but it is hard to make a determination without an exam.  If you continue to be worried, phone your plastic surgeon's office for guidance.
