Possible incoming labor?

So. I know I post a lot. I'm getting restless. I'm due in 12 days.

I was 1cm Thursday.

I had contractions ALL morning today, some were taking my breath away. and then they slowed down and got less intense around noon.

But now I'm SO nauseous and I feel like I have to poop, but nothing or very little comes out. My stomach hurts, but not like contractions, it's more like. When you have a stomach bug? Or like when you have AWFUL gas. It's kind of burning, y'know? On top of the actual contractions.

And my lower back hurts so badly I can't get comfortable

I don't know what to make of any of it. At all.
