What Can I Take To Recover From A Week-long Cough With Green-to-yellow Mucus Be Bronchitis?

Hi. I thought I had the flu but now I'm afraid I may have Bronchitis. I have been sick about 1 week. Slight fever, chills, sweats, body aches and a persistent cough. I was coughing up Green mucus but yesterday it's turned yellow. I feel slightly better today but still have a deep cough that hurts. What can I take to get better?
