Do i have swine flu please answer?

I got sick a few days ago but i don't know if its just a cold or the flu or swine flu. It started with me having really bad chest pains and a cough that made my throat really sore. Then I started getting chills and feeling achy all over while the other symptoms got a little better. Then after about a day I was feeling almost completely better and then I started getting achy again and now I sneeze and have to blow my nose alot. Is it swine flu, or just a cold? or just the plain flu?
