Could this be bronchitis?

I have been coughing for a few days now. it's a dry cough for the most part, and I have also had a headache for the last two days (ibuprofen helps). Today I am really tired. I don't really think its the flu, no fevers or aches. I am thinking maybe bronchitis, I had it a few years ago but i don't remember how it started and didn't know i had it until it was kind of bad.
