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.

When will labor start if you are 1-centimeter dilated? Most of the time, the cervix is a small, tightly closed hole. It prevents anything from getting into or out of the uterus, which helps to protect the baby.
During labor, intense contractions of the uterus help move the baby down and eventually out of the pelvis, and into the vagina. These contractions put pressure on the cervix and cause it to expand slowly. Contractions tend to get stronger, closer together, and more regular as labor progresses. Most medical guides divide labor into three stages :. In the early stages of labor, the cervix dilates to the following sizes :.
Late in pregnancy, the cervix may have already dilated several centimeters before a woman experiences any symptoms of labor. Some women, particularly those who are giving birth for the first time, have difficulty telling whether labor has begun. This is because contractions in early labor are often mild and irregular, growing steadily more intense as the labor progresses and the cervix dilates.
This increase in intensity may take just a few hours or can take many days. Knowing whether this is actual labor can help people to prepare. Some women may benefit from resting or eating a snack at this stage to ensure they have enough energy for the more tiring stages ahead. During the active stage of labor, the cervix dilates to the following sizes :. Labor contractions become more intense and regular during active labor. Many women find that the main characteristic of active labor is that the contractions are extremely painful rather than uncomfortable.
At this stage of labor, some women may choose medication, such as an epidural to cope with the pain. Others prefer to manage the pain naturally. Changing positions, moving, and remaining hydrated can help with the pain of active labor. During the transition phase of labor, the cervix dilates to the following sizes :. For many women, transition is the most challenging stage.
However, it is also the shortest. Some people begin feeling an urge to push during the transition stage. It is also common to feel overwhelmed, hopeless, or unable to cope with the pain. Some women vomit. Some women find that the coping strategies that worked well in the earlier stages of labor are no longer useful. Transition tends to be short and is a sign that the baby will soon arrive. These signs can be expected around your due date. It is perfectly normal for labor to begin 2 weeks before or 2 weeks after that date.
When the baby drops or "lightens," they move lower into your pelvis. It will ease pressure on your lungs and stomach. You may find it easier to breathe.
Heartburn may also decrease if it had been a problem. However, pressure on the bladder will increase. You may need to urinate more often. This may happen many days or weeks before any contractions. Dropping is determined by the doctor during a pelvic exam. The doctor will describe how far your baby has dropped using stations:. Effacement is the thinning of your cervix. The cervix is the opening to the uterus where the baby is carried during pregnancy.
You cannot feel effacement. The doctor will measure it during a pelvic exam. Effacement is reported as a percentage. The cervix must open, or dilate, to allow the baby to pass.
It is measured from 0 to 10 centimeters cm. Dilation may begin slowly in the days or weeks before birth. Once active labor begins, the cervix dilates to 10 cm. You will not feel dilation.
Your doctor will measure it. Delivery can happen before reaching 10 cm if the baby is preterm and smaller than a full-term baby. A thick plug of mucus fills the cervical opening during pregnancy. This plug is here to keep bacteria out of the uterus. As the cervix thins and opens, this plug may fall out. It may appear as stringy mucus or a thick discharge that is brown, pink, or reddish.
Labor usually begins within 72 hours of this show. The baby is surrounded by a fluid-filled sac called the amniotic sac. This sac can break before labor begins.
You may feel water running out of you or your underwear may be constantly wet. The flow can be dripping or gushing. The doctor should be called once water has broken. These are contractions may occur toward the end of pregnancy.
They may help your body get ready for the real event. Not everyone will have braxton hicks. The contractions may become stronger and more painful as you near your due date. There are a few ways to tell Braxton Hicks false labor contractions from contractions of early labor:. Labor and delivery often progresses through 3 stages. The first stage of labor starts when true labor contractions begin.
During stage one, the cervix dilates and effaces to prepare for birth. This stage is divided into 2 phases. Phase 1 is called early labor or the latent phase.
The cervix is dilated from 0 to 3 cm. Mild to moderate contractions may be coming every 5 to 20 minutes. It can cause a backache, feeling of fullness, or menstrual-like pain. Phase 1 is the longest section of labor.
