Has anyone gone into labor before their scheduled c section?

Has anyone gone into labor before their scheduled c section? I had an emergency c section with my 1st at 35weeks. I never got to experience the contractions and "going into labor" stuff.. With this baby I'll have a scheduled one.

I keep seeing birth stories for all you woman going into labor early I'm scared and curious what to do, how long you wait to go to the doctor ( I'm delivering at a hospital 45min away) and if a c section is still possible if I've gone into labor.
