Everything you need to know about....
THE CERVIX
Did you recognise it from this photo? Good old, trusty cervix.
Birth stories are always littered with "I was 5cm when I was admitted", or "I was only 3cm so was sent home" (let's not start on the use of "only" at this point....that's a whole other post)
We are OBSESSED with how dilated the cervix is during labour (no one ever wants to know how effaced you were, or its position when you tell yous birth story), but do you have an idea of HOW It opens up?
Many of us often picture it as this hole that just gets wider and wider of it's own accord, but that's not entirely true....
..imagine you are putting on a jumper. The head hole looks pretty small when you get it out of your wardrobe, but as you pull the jumper over your head, the opening slowly gets wider and wider until *pop* your whole head comes through - THAT'S more like how the cervix works.
With each contraction the muscles of the uterus that run from the cervix to the fundus (the top) contract, and become slightly shorter each time. This shortening has 2 main effects:
1. A gathering of uterine muscle at the top of the uterus (fundus), and
2. The gradual opening of the cervix, pulling it over the head of the baby.
So what does knowing the dilation of the cervix tell us?
..............well.......not a huge amount in an uncomplicated physiological birth. Being 2cm dilated doesn't mean your baby can't be born in 15 minutes, same as being 9cm doesn't mean you've not got 10 hours left!
"Your cervix is not a crystal ball"
This is one of the reasons I encourage everyone to consider whether they would like to consent to routine vaginal examinations or not.
