How long after?

How long after finding out that you were 1cm dilated did you go into labor?

I know with some people they were 1cm dilated for weeks and others didn’t dilate at all.

I’ve been having contractions on and off since 30 weeks and was diagnosed with preeclampsia and go to regular non stress tests twice weekly. I wasn’t dilated before 34 weeks, but I’m not sure when I started dilating but at my 36 week check up I was 1cm and having some painful contractions. I’m 37 weeks today and the contractions aren’t consistent, but definitely getting really painful
