37 week checkup...

Kyleigh • 23, and a mommy to 2 beautiful baby girls! Avery London born May 5th, 2016 💕 Makayla Rhae born May 27th, 2018 💕
And my doctor said I'm more dilated on the inside of my cervix than I am on the outside. I still am dilated at 1cm tho. Can someone please explain to me what this means?
