4th baby and never experienced this before.

I have a tightening pain in the upper stomach, round my ribs and round to the middle and bottom of my back.

Sort of Feels like I've got a corset on around that area and someone keeps tightening it.

I was only laying down trying to nap and its started out of no where.

Also making me feel really nauseous

Anyone experienced this?

I've never gone into labor naturally.

Tried googling but it all talks about lower abdominal pain
