How long after being exposed to swine flu would I see symptoms if I had it? - flu symptoms more condition_symptoms

So I worked closely with a colleague yesterday for several hours. Today she came to work because he was sick, went to the doctor and he thought it was swine flu. When I found her when she starts to show the symptoms? What are the first symptoms? I know that after experiencing the obvious symptoms, but I think something that we could not ignore a cough or something.
