I’m not a medical professional, as of now, but, I can suggest you stay hydrated for the time being. How long have you been coughing up?

A dry cough is hoarse.

Pneumonia:

“With pneumonia, you may cough up phlegm that is yellow, green, or sometimes bloody. Your symptoms will vary based on the type of pneumonia you have. Cough, fever, chills, and shortness of breath are common symptoms with all types of pneumonia.”

Also

If you have pneumonia, you’ll be unable to lie flat due to the buildup in your lungs. You’ll also have shortness of breath upon exertion.

If you can, check your temp morning afternoon and before you go to bed. If you’re running a fever for more than a day, I suggest you receive attention. Btw, this is pure assumption.
