Back/hip pain sorry posted in the wrong group...

Kaitlyn
I'm having some pretty serious back and hip pain that is shooting down my legs to my knees. I've been swelling and puking all day, my belly has been cramping a little every now and then but nothing consistent. Should I call my doc? Is this a sign of labor? I'm 34&2 but baby has been measuring a little over a week ahead my whole pregnancy.
