Do I have Bronchitis?

I have had a viral infection for 5 days. I went to the doctor on Monday (three days ago) and he said I would be better by now. My fever, stomach ache, and headache are all gone but I have been coughing a lot. most of them are dry coughs, but if I cough really hard I can get some phlegm out but that doesn't help me stop coughing! Should I get a cough suppressant, or go to the doctor again? Do I have Bronchitis?
