Chest tightness/congestion with covid while pregnant

Feels like I can’t inhale all the way in when I need to cough without feeling winded. Did any of you experience this with covid while pregnant? If so, what did you use to clear it up? I’ve called the after hours ob line and the nurses can’t tell me anymore than what i already knew before I called such as reading the medication list. Then when asked if I can take one of the meds that’s listed with baby aspirin as recommended by the doctor, they have no clue SMH.
