I don't have much conscious memory of pain. I do have though, what I'd call "body memory." Sometimes I dream about birthing my babies and the sensations feel very, very real, so that I'm shocked to wake up to no baby.
During my 3 subsequent pregancies after my first, towards the end I always have more and more BH contractions. I'd wonder and wonder if they were labor, because I couldn't remember exactly what labor felt like. Yet, every time I started real labor, within a contraction or two, I'd think "Oh yes, THIS is what it feels like." My body remembered, even though my mind couldn't.
The end of my last labor was more painful than some of my others. The sensation of crowning, and having my dd kick me for the last time after her head was out were very intense. After she was born, I'd concentrate on remembering exactly how it felt every day, trying to keep the memory conscious, especially since I knew she'd be my last. Despite, that, though, the memory has softened and faded. I can remember that it was intense and amazing, but I can't fully recall it anymore.
Does that make sense?
