Stomach cramps. Food poisoning? Flu? - stomach cramps from the flu

Yesterday afternoon, I ate chicken that was a little old. Today, 24 hours later, I had stomach cramps, (even 24 hours later) had a loose BM. Mylanta seems to have settled a bit. Could it be chicken so late? I had a vaccination against the flu a month ago. Could not the flu?
