Did I have a heart attack?

I've had a cold for the past 4 days and I thought that it went into my chest because when I woke up this morning, my chest felt heavy. I took some cough medicine and then within a couple of minutes my chest started to hurt in between my and I got really nausious then I got really clammy. Then after about 5 minutes it went away. I don't know what to do or what it was. My chest doesn't even feel heavy anymore.
