I've Had A Cold For 2 Weeks Now. Symptoms Such

I've had a cold for 2 weeks now. Symptoms such as runny nose, stuffy nose, tiredness. I thought it went away but this week i have cough. Its not only a cough but its a sore throat with some minor chest pains as well and every once in awhile i couch of some mucus. I wanted to know if it's just a cold or is it more. Is there any over the counter medications you would recommend? I rather not go to a doctor but if my symptoms don't go away within the next week I'm willing to go and see a doctor.
