If this isn't your first baby - how's your body feeling?

I remember feeling slow and like my hips were spreading toward the end with my first pregnancy, but with this second time, it feels like baby could just fall out at times if I walk too fast. I'll be 37 weeks on Monday. Just wondering if other second or more times mamas are feeling the same. I keep thinking I have to be going early given how it feels sometimes, but could so definitely be nothing of the sort, too.
