Anybody else feel like they can't breath sometimes?

Marissa • I'm just as lost as anybody else • Taking my life day by day

Like as if the baby were squishing my lungs, but is that even possible? First time it happened it woke me up, I was gasping for breath and freaking out, it felt like someone had been choking me! Mostly happens at night, but sometimes throughout the day while I'm sitting down, I suddenly get alot of pressure on my chest and I become short of breath.

Anybody else experience this?
