$50 JJ Can I play this profitably?

[Chargers In 07]

Villain is 0/0 after a whopping 6 hands. This is only my second hand at the table. First hand there were 2 limpers I raise from bb to $3 get 2 callers, they fold to c-bet. In this hand I feel I'm probably ahead but if we get arrrr in I'm going to be behind.
