Labor in second pregnancy

Hey ladies so I'm pregnant with my second kid and I just hit 35 weeks and I feel like there's a huge difference from just 33 weeks till now. My back hurts like crazy, my hips hurt, it hurts to walk and move; sometimes it feels like my bones are almost cracking in my lower back when I shift around or go from laying down to getting up. Braxton Hicks are crazy too! So different than my first time! 
Anyways for any ladies who have more than one kid how far along were you when you went into labor and did you get earlier signs of labor or how different was the time leading up to labor.
With my first I went into labor at 40W5D but gave birth at 40W6D; labor lasted 25.5 hours from when contractions started.
