Third baby already been to L and D dilated to one

Hi ladies!

This is my third baby! My first two I went into labor naturally around 38 weeks

First baby boy was born at exaclry 39 weeks after several days of labor

Second baby boy was born at 38 weeks and 2 days

I was never dilated prior to that I was really always a zero pretty much until I got to week 38

Baby girl caused some drama last night so I was in labor and delivery for a long while trying to slow contractions I was dilated to a 1 and I will be 35 weeks Saturday. They weren’t worried saying it’s normal. Anyone else dilated this early ever before and what happened?!? Still contracting today but it’s not every five minutes like last night was!
