Random gasps for air??

I’m 32 weeks and some days. I’ve been doing this thing lately, especially when sleeping when I’ll be breathing normally and then all of a sudden I take a huge gasp of air. Like I am gasping for air. Idk. It’s weird. I don’t know the best way I can describe it is that she’ll be sitting in my lungs or pressing up against them so I’ve been used to short breaths and then all of a sudden she will move off them in my longs fully expand and grab as much air as it can..

Anyone else have random large gasps for air?.... or I’m just crazy 😂
