Second baby 37 weeks today 1cm 80% effaced

K

So first baby water broke suddenly at 37.2 no contraction and when checked was only 1/2cm dilated and no effacement had baby vaginally 23 hours later. I gave birth to my first 15 almost 16 months ago and so with baby number 2 I got checked today and was 1cm 80%. Any second timers end up going in to labor soon after? Or dilate quicker once contractions did start because they were already pretty thinned out?
