24 weeks & breathless

I’m 24 weeks with baby #2 & I’ve been feeling very short of breath.

It’s constant. I’m currently wide awake at 1am right now because I can’t get comfortable because I feel like I just can’t get enough oxygen. The simplest tasks like walking to the bathroom from the living room have me breathing heavy.

I know it’s a normal part of pregnancy but is there anything I can do to get some relief? I’ve propped myself up with pillows so I’m elevated hoping that would help but I still feel so out of breath.
