Mama’s with Asthma?

Is there anyone out here dealing with asthma and pregnancy? I’ve taken prednisone, using my inhaler, done breathing treatments. My oxygen is 99-100% but I feel like I cannot breathe at all. I struggle to get that air in. It’s not deep in my lungs it’s in my chest it feels like. Is this just want being pregnant with asthma is like? None of my docs seem concerned since I’m getting enough oxygen; but this is interfering with my daily life and having to chase around a 22 month old. Any advice from those who also have asthma is much appreciated.
