I recently got bell palsy 3 weeks after my moderna covid vaccine and i am do for the second dose. should i wait for the second dose or should go ahead with it?

Bell’s Palsy tends to be a potential post viral syndrome. Might be prudent to get evaluated by PCP or Infectious Disease Consult before further procedures

This may or may not be secondary to vaccine as most often Bell's palsy is secondary to herpes virus. Probably could safely take second dose, but not clear how this is being managed, so, delay until a neurologist or infectious disease doc has cleared you.
