Side stitch/ cramps

Brittany
Ok, so I found out I was pregnant a few weeks ago. I've been doing very well at keeping active. However, when I am doing power walking, I constantly have side stitches! (This is what my family always called it??--- like the cramps in your sides when you are running or walking) does anyone else have this feeling in their sides/ abdomen?? I also felt it at my brother in laws wedding when I was dancing. I think my abs are already moving and changing?? Is that possible?
