As labor approaches, cervical effacement may be accompanied by pre-labor symptoms such as:. Once labor is fully underway and your cervix moves toward full effacement and dilation, you'll experience accompanying labor symptoms such as regular, more intense contractions.
Your water will "break" if the amniotic sac that surrounds your baby ruptures. When your cervix is 1 cm dilated, it means your body is preparing for labor, or is in the very early stages of labor. It's impossible to know how quickly your cervix will dilate further. It could be a matter of hours. But it could also take a few days, or even weeks. As with 1 cm dilated, being 2 cm dilated doesn't mean that labor is imminent. Some women who are 2 cm dilated may go into labor within hours.
Others will remain 2 cm dilated for a few days or weeks until labor progresses. Once your cervix reaches 3 cm dilation, you've probably entered the early stage of labor. During this stage, your cervix gradually dilates to about 6 cm. This is the longest part of labor and can take anywhere from a few hours to a few days, although between 8 to 12 hours is common.
Once you reach about 6 cm dilation, you're in the active stage of labor. At this point your contractions become very regular, longer lasting, and more painful. You probably won't know when you're precisely 6 cm dilated. However, as a general rule, you'll want to call your provider and possibly head to the hospital or birth center when you've had regular, painful contractions that each last about 60 seconds and occur every 5 to 7 minutes for at least an hour.
During the active stage of labor, your cervix dilates from around 6 cm to the full 10 cm. The last part of active labor, when the cervix dilates fully from 8 to 10 cm, is called transition. This process takes about 5 to 7 hours if you're a first-time mom, or between 2 and 4 hours if you've had a baby before.
The exact duration of this stage is different for everyone. Once your cervix is 10 cm dilated and percent effaced, you're ready to start pushing. You'll probably feel a strong urge to push at this point. When your cervix is 50 percent effaced, it's about 2 cm long. At this point, it's halfway to becoming short and thin enough to allow your baby to pass through the uterus and into the vagina.
Most effacement usually happens during the first stage of labor, when your cervix is dilating to 6 cm. This process can take several hour or days, and will likely be accompanied by early signs of labor such as Braxton Hicks contractions and losing your mucus plug. When your cervix is 60 percent effaced, it's 60 percent of the way toward becoming short and thin enough to allow your baby to pass through the uterus. Most of the effacement process happens during the early stage of labor when your cervix is dilating to 6 cm, and may take several hours or even days.
A cervix that's 70 percent effaced is 70 percent of the way toward becoming short and thin enough to allow your baby to pass through the uterus. This process typically happens during the early stage of labor when your cervix is dilating to 6 cm, and may take several hours or even days.
Once your cervix reaches 80 percent effacement, it's almost short enough to allow your baby through the uterus, assuming it is accompanied by dilation. You may reach 80 percent effacement or higher during the early stage of labor, or this may happen once you reach active labor. The same is true for 90 percent and percent effacement. Either way, effacement and dilation must both happen completely before you can begin pushing. In other words, you must be percent effaced and 10 cm dilated for your baby to pass through the birth canal.
You're only 20 percent away from being fully effaced at percent, which is when you're ready to deliver. Your cervix is preparing for delivery by providing an opening from the uterus to the birth canal — unblocking the path to your baby's exit route.
Beginning in your ninth month of pregnancy, your practitioner will look for clues that labor is getting closer, palpating your abdomen and giving you an internal exam to check your cervix. In addition to seeing if baby's dropped , she's confirming whether your cervix has dilated and effaced and if it's begun to soften and move toward the front of the vagina — another indication that labor is getting closer.
Keep in mind, it's not a problem if your baby hasn't dropped just yet; a vaginal delivery is still definitely possible. Based on these factors, she'll likely make an educated guess as to when you'll deliver. But don't go racing to the hospital just yet if that guess is "soon. As the cervix continues to thin and open, the "cork" of mucus that seals the opening of the cervix , otherwise known as the mucous plug, becomes dislodged. You may or may not notice it happen, and it can occur anywhere from a couple of weeks to hours before labor starts.
Then, a few days to 24 hours before delivery day, you'll notice bloody show as the capillaries in your cervix begin to rupture, tinting the vaginal mucus pink or streaking it with blood. When labor contractions get progressively stronger and don't go away even when you change positions, you'll know it's finally show time! Throughout this process, your cervix will keep on effacing and dilating.
In early labor — those days to possibly weeks before it's time to go to the hospital — your cervix will dilate up to 6 cm; by active labor it will increase to about 7 to 8 cm. Full cervical dilation — when your cervix measures 10 cm — occurs at the end of the transitional phase, the last of the three phases of labor. Once this happens, it's time to start pushing your baby out. Not a thing: Your body is in charge here. Once your doctor gives you that estimate for baby's arrival, just keep an eye out for other signs of labor so you'll know and be prepared when it's time to go to the hospital.
Occasionally if labor stalls or if you have certain risk factors, your practitioner may decide that there's a reason to induce labor and will take steps to move the process along.

Losing the Mucus Plug: During pregnancy, a glob of mucus seals the cervical opening shut, and it protects your baby from outside germs and bacteria. As effacement and dilation progress, you may notice your mucus plug pass through the vagina. The mucus plug usually looks like a thick, gelatinous, yellowish-white substance, and it can also be tinged with blood.
Bloody Show: As delivery nears, the blood vessels in the cervix capillaries will rupture, tinting your vaginal mucus with blood. This means labor will start sooner rather than later! Pelvic Discomfort: Women may feel a small pressure from cervical dilation and effacement, says Brichter. However, cervix dilation pain is extremely rare.
Your practitioner will measure cervix dilation and effacement during your prenatal appointments, usually with gloved fingers. But even if your cervix has started to thin and open, when you'll actually go into the active labor phase is still a mystery. By Dr. Laura Riley Updated July 29, Save Pin FB More.
