Can you still get the flu if you've been vaccinated?

i've been vaccinated against the regular flu and swine flu but my entire body is achy and i'm running a fever. i thought it might be stomach flu because my boyfriend had that like a week and a half ago but i don't feel nauseous and he didn't say anything about body aches. i was vaccinated maybe a month and a half ago and i know the incubation period is like 10 days, is it possible that i have the flu?
