I am not a doctor so I can't tell you about whether or not you have mucous, but inflammation is really part of the disease. One thing that you might want to add to your supplements is Vitamin D3 if you do not get out into the sun at least 20 minutes a day. One tablet a day is enough.
Don't start worrying about every bug there is out there. Most people that get pneumonia have a fever, but not always. Some report chills, cough, spitting up blood, severe headache. Bilateral is just another way of saying double pneumonia. This means both lungs were infected. You will know if you have it because you will be very ill. It will be hard to breathe. There are antibiotics that can help you in most cases. Concentrate on feeling well and not ill and it will help Carmen. Worrying is stressful.
