Can you be 50 effaced and not dilated?
Furthermore, does 50 effaced mean Labor is near?
During labor, you might hear your healthcare provider say something like, “You're 50 percent effaced.” This simply means that your cervix has thinned out to 50 percent of what is considered fully effaced. So, if you hear your healthcare provider say this, you are half way to 100 percent effacement.
Also question is, how long can you be 50 percent effaced?
When it is 50 percent effaced, it is about two centimeters long. When it is 100 percent effaced, it is "paper-thin." Effacement can happen over days before labor starts. Or, it can happen over hours as labor progresses.
Effacement means that the cervix stretches and gets thinner. Dilatation means that the cervix opens. As labor nears, the cervix may start to thin or stretch (efface) and open (dilate). This prepares the cervix for the baby to pass through the birth canal (vagina).
