Squid allergy/reaction..really need help?

I'm on vacation with my family and last night I tried calamari(which was fine becqu�e n� one else got sick). A few hours later I started to feel sick, but I thought I was just 'getting sick' anyways. Ive had major stomach aches all day and a few hours ago my lips turned white, I had a fever, puked, and then fainted.. I feel better now. Am I allergic? Is it possible for the reaction to be that delayed? Any ideas? im in another country, or I'd just got to my doctors. Thanks :)
