Having first exascerbation and don't know what to expect

I was diagnosed with mild BE and ILD in January of 2025. A broncoscopy found a lot of Pseudomonas and some MAC. At that time watchful waiting was recommended since I had very little coughing or SOB. I went along with nebulizing and airway clearance 2x a day. My scans and lung function tests were pretty stable since first getting sick with pneumonia in Sept, 2023. In January 2026, I changed insurance from Kaiser to original Medicare and was able to go to Georgetown, which is a center of excellence near me. At my first appointment I was told that I had traction bronchiectasis caused by lung scarring. We could continue the watchful waiting.
In mid August 2026, I suddenly got hit with fever, and terrible malaise. I just wanted to be in bed. Since I live alone, I thought I'd better try to figure out what this was. I looked up symptoms for flu, covid, and pneumonia and they didn't seem to fit. My coughing and mucus had been slowly increasing for several months, but I hadn't been feeling bad. I had mentioned it to my new pulmonologist in March and July when I saw her, but she didn't seem concerned. I gave my first sputum sample in time to be finished by July. There was nothing, but I have a lot of trouble getting sputum up into my mouth. I always know it is there because I swallow it.
This time in August I had more sputum than I had ever had--still not a ton, but enough that I was able to collect it. The following day I took it to Labcorp.
Results came back that I had pseudomonas and the doctor prescribed levofloxacin. I started feeling better by the next day and by the end of the course, I had no fever. I also had virtually no coughing or sputum, even when I nebulize. The only thing left is weakness and some SOB when I exert myself.
It has been 5 days since I stopped the Levofloxacin and I still have no coughing or sputum. Is this how it usually goes? I have not had any antibiotics to treat this before. I'm wondering if it is a good thing or a bad thing not to cough up the mucus. It is my understanding that it is important to get some of the bacteria out.
I understand that we are all different in how we respond to anything related to this disease, but I would really appreciate hearing from others who have had a somewhat similar experience and how it went for them.
While I like my new doctor very much it is REALLY hard to communicate through the system, so I am expecially grateful that this group exists!!
