In brief: Unlikely pneumonia

Bronchitis is usually due to a virus.
With pneumonia you are very likely to develop fever, cough with sputum containing pus and/or blood, difficulty breathing, sometimes chest pain on inspiration. A thorough exam by your primary care doctor is in order, and if they feel necessary, a chest x-ray.

In brief: Very different

Telling "walking" pneumonia from bronchitis is often straightforward.
Cough with no fever for 6 weeks is very typical of bronchitis. Pneumonia of any kind will almost always have a fever. Pneumonia also has very distinctive features on a chest x-ray. This is why docs always wanna take a chest x-ray on kids with cough and a fever. See your doc for diagnosis and treatment.

In brief: Probably alternative

The difference between acute bronchitis and walking pneumonia is degree of symptoms.
With symptoms present for that long and no fever, the diagnosis is probably not an infection. You may have similar symptoms with allergies and there is treatment for this so see your doctor for evaluation.
