Possible labor soon??

Have any of you moms out there (who have already had a baby, or are getting close to your due date) felt like an animal that is going to have its baby? Like you know how animals get? All antsy and moving constantly? I guess I'm comparing it to a dog about to have pups. They go in circles a lot, make up their little beds, and just look uncomfortable. That's how I'm feeling today and it's concerning. Help!!!!!!
