Contracting vs. Not Contracting: A Visual

This was my belly a little over a week ago, at 19.5 weeks, not contracting.

The shape of my belly changes as I have a contraction.

As pregnancy progresses, some contractions become so obvious that even outsiders can tell a difference. A couple years ago, when I was 35 weeks with Haley, I was at a scrap-booking event with a friend. As a contraction began (they were about 10 minutes apart and very strong that day), I sat back in my chair and rested a moment. A couple ladies across the way (about 10 feet away) looked at my belly and asked, "Are you having a contraction? . . . Because your belly looks really odd." It did. It was contorted and almost boxy--like my uterus had corners to it! I have no idea what was going on during that contraction, but I sure wished I'd brought my camera!
