36 weeks 3 day on cervix check

Amber • EDD August 28, 2017 with baby #3

Ok so this is my third baby but it has been 8 years since I delivered so a little help please lol. I am a solid 3 cm pushing 4 by my cervix is more cone shaped and he said I was super stretchy and not hard. He said he won't stop my labor if it happens... baby is measuring 80th percentile. My question is about my cervix and the cone shape and super stretchy comment... what does that mean? He didn't mention effacement just said that I was a 3 cm inside and 4 at the beginning.....
