PLZ share…how long did it take you to go from 2.5 cm dilated to established labor where they admit you?

I was 2.5 cm 2 days ago and had a sweep done, but when I got checked today, it was still nothing. I’ve only had on and off contractions since then, that made me want to go get checked, with no other symptoms. I’m scheduled for an induction tomorrow if I don’t go into labor on my own, so I am nervous hoping someone can tell me it happened fast for them.
