Super weird

I keep getting this random suddenly kinda hard to breathe wheezing that makes me cough to try to breathe. It only lasts a few second and sometimes repeats itself every min or so till it goes away and then comes back again later. Idk if it’s normal but it doesn’t feel normal. I’m 24 weeks and I keep thinking maybe baby is hitting my vena cava weird but idk is he too small for that yet? I never lay on my back but I do notice it more when I’m laying or sitting
