Does anyone else have it this bad?

Rose

I'm 26 weeks and 4 days. This is also my second pregnancy.

I had my first child July 20th, 2012

I was 20, overly fit, and had no sicknes, no contractions, etc. The only thing to happen was I swelled up like a fat hog. My legs were twice the size they normally were and doctors said it was just water weight probably.

Now I'm on my second kid, I broke my back last year(April 2015) and wondering if its just me, but I've been EXTREMLEY nauseas. And the pain, its like someone is trying to crack my pelvic bone in half vertically. I'm pretty sure some of my pain is from my previous C-section scar. But I feel like my pain is worse than it should be. The pain goes to my legs and I can't walk, and I feel worse than when I Broke my back.

Is this normal or are my doctors maybe crazy/not caring?
