Can Your Cervix Uneffaced?

In some women, the cervix may start to efface and dilate slowly over a period of weeks. But a first-time mother often will not dilate until active labor starts. Late in your pregnancy, your health professional may check the cervix with his or her fingers to see how much it has effaced and dilated.

Can your cervix close once dilated?

One woman may go from having a closed cervix to giving birth in a matter of hours, while another is 1–2 cm dilated for days or weeks. Some women do not experience any dilation until they go into active labor. This means that the cervix is completely closed initially, but it widens to 10 cm as labor progresses.

Can you feel your cervix thinning?

Effacement: Thinning of the cervix

As labor begins, your cervix softens, shortens and thins (effacement). You might feel uncomfortable, but irregular, not very painful contractions or nothing at all.
