most likley the baby dont like you laying on your back the perfer on your side and ya i am the same way but i also get really bad heartburn and stabbing pain when i lay on my back but you just have to get used to laying on your side for now on cause its not about you being cofterable its about the baby

Ouch if it feels like BH just keep readjusting yourself or get up and walk around a bit

mine is just like a super painful BH and my stomach gets really hard. @kzp

If I'm on my back I try to sit up some because it feels like something is pressing down on my chest and tummy when I lay flat

ugh it just started late last night but the baby is still moving so I wasnt to worried just annoyed. @kzp

Yes I can't lay on my back at all
