Did anyone go into labor before their scheduled c-sec and want to share their stories?

I'm having a repeat (medically necessary) c-section. My first DS was scheduled (and delivered) at exactly 39w. This time, my scheduled date is only 2 days before 40w and I'm totally freaking out that I'm going to go into labor before that and have an emergency situation that I'm not prepared for.

Is the experience any different? I'm super anxious about it and due to their schedules, they can't move it up (and won't go a day over 39w)!
