Why do i need to sleep sitting up?

I’ve realized with this baby I can only sleep if I’m on my lazy boy reclining couch which partially sits me up. The bed with pillows doesn’t cut it. As soon as I lay on a flat surface I either can’t get comfortable or immediately start vomiting.

If I have any chance of getting sleep I have to be on the couch.

With my last two pregnancies I didn’t start sleeping sitting up until month 8 or 9 when the pressure on your back is too much so it’s easier to sleep in a lazy boy than try to get comfy with a big ole belly. But it seems strange that this time I’m vomiting if I lay down this early on 🤷🏻‍♀️🤦🏻‍♀️🤰🏻
