2nd baby arrival?

Who here has had their 2nd baby come faster than their 1st? And did they come earlier? My first came a few hours after his due date and now I'll be 37 weeks with my 2nd on Tuesday. My dr is supposed to start doing cervix checks at 37 week appt. I've done a lot of walking this weekend cause we are moving next weekend and have been feeling lots of pressure down low and my hips are killing me now, I feel like he's dropped down from walking so much. I'm just wondering if he will come sooner than my 1st did.
