Repotting is not a good solution if you want it to flower. Flowering is a pepper's way of ensuring it continues to survive (flower > fruit > seeds > new plants). If the plant becomes pot bound then it starts the process of reproduction. However giving it more room to grow will often have the opposite effect where it continues to produce greenery rather than flowers.

I'd say sit back and watch. As long as the plant/leaves looks healthy then you've nothing to worry about. As Kristen says though, a high potassium fertilizer could help too.
