Welcome to ehealthforum.
After completion of 37 weeks of pregnancy, you can go into labour anytime. There will be changes in the cervix, vaginal canal and the bones in the pelvis. The most obvious being the changes in the cervix. With the baby entering slowly into the pelvic cavity, the head of baby will press on the lower uterine segment and the cervix causing elongation of the lower uterine segment and taking up of the cervix. This causes thinning of cervix along with opening up of the cervical canal. The thinning up and taking up of cervix is called as âeffacementâ.
In your examination result, 1cm dilated means that cervix is opened up to 1cm. It will slowly open up more (get effaced and dilated) to allow for active labour pains to set in resulting in final expulsion of baby/delivery.
Hope this helps. Take care
