Baby Dropping & Labor

Brittney • Mommy of 2. #Son&Daughter
How many weeks were you when your baby "dropped", and how long after that did you go into labor?
For second time moms im reading that it doesn't happen until right before labor. I was having a pain today at the top of my stomach whenever I would touch it, it's either sore or my skin is just stretching. But when I got home tonight I noticed that my baby has dropped or she is definitely a lot lower than she was yesterday! The space between my stomach and boobs is a lot more noticeable. 
I'm 37 weeks today and I'm not ready to go into labor yet so I'm nervous!
