They feel like really bad period pain in your back. The pain doesn't stop between contractions. It's a constant painful painful ache. All in your lower back. As labour progresses they can make it hard to move around. This is all from my experience of an 8 hour posterior labour with a full OP vaginal birth. I'm sure other people may have experienced them differently. Hope that helps why do you ask?
Same! Mine got that bad that when the actually contraction hit and the pain intensified, I would just about loose the strength in my legs. At one stage I was told to lay down *shock* and the pain was a million times worse and i kept trying to roll to one side. poor DH was having a tough time keeping me on the bed.

With DS#1 I got a lot of back pain and I would get down on all 4 to drop him forward...soemtimes it would be quick other times it would take ages to get him to move!
