Is this Asthma?

2 years ago had SOB so bad though I was going to pass out. It was pneumonia. SOB persisted in brief episodes for months after getting and sick. A body spray that I used for years started giving me full blown attacks. I then went like a year without any issues. Today I randomly started getting out of breath. As it progressed I left class to go to my apartment to see if I still had my albuterol inhaler from over a year ago. I luckily did, because I could barely make it up my stairs. Does anyone have similar experiences? I’ve never been tested for asthma or diagnosed. It started after I got pneumonia and has been so inconsistent. It’s weird
