During pregnancy, your cervix is about 3. As your body gets ready for labor and once labor begins, your cervix gradually thins out until it's like a sheet of paper. Providers describe effacement as a percentage, from 0 to percent. When your cervix is fully thinned, you're percent effaced. Effacement happens hand-in-hand with dilation, although effacement may begin first. As with dilation, it can take weeks, days, or hours to reach full effacement.
Once your cervix is percent effaced and 10 cm dilated, you're ready to start pushing your baby out into the world. Everyone is different. If this is your first pregnancy, your cervix may not start to dilate and efface until you go into labor and contractions begin. Or it may start to efface, but not dilate. Or, your cervix may start to efface and dilate gradually over several days or weeks toward the end of your pregnancy as your body prepares for labor.
During labor, and sometimes before, your doctor or midwife may check your cervix to see how much it has effaced and dilated. He or she will do this using his or her fingers, and wearing sterile gloves. Once your cervix has started to dilate and efface, labor is approaching. However, if you are just 1 to 2 centimeters dilated, or below 50 percent effaced, it could still be days or weeks before labor actually starts.
To know when it's time to head to the hospital or birth center, you'll need to watch out for other signs of labor. You may not feel anything when your cervix first starts to efface and dilate, especially if the process begins before you go into labor.
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. Labor pain may radiate around the abdomen, back, and thighs.
Your cervix will also dilate from around four to seven centimeters. First-time moms experience active labor for around three to six hours; it generally lasts one to three hours for subsequent pregnancies.
Moms-to-be can expect intense contractions during the transition phase—and possibly nausea, pelvic pressure, shakiness, and fatigue as well. Your cervix will finish effacing and dilating to the full 10 centimeters. This phase lasts anywhere from 10 minutes to two hours. Your doctor will update you on cervical dilation progress throughout labor, but it can be hard to imagine your lady parts opening, say, 4 cm or 8 cm.

When your cervix is fully dilated, your baby will move further down the birth canal towards the entrance to your vagina. You may get an urge to push that feels a bit like you need to poo. You can push during contractions whenever you feel the urge. You may not feel the urge to push immediately.
If you have had an epidural, you may not feel an urge to push at all. If you're having your 1st baby, this pushing stage should last no longer than 3 hours. If you've had a baby before, it should take no more than 2 hours. This stage of labour is hard work, but your midwife will help and encourage you. Your birth partner can also support you. When your baby's head is almost ready to come out, your midwife will ask you to stop pushing and take some short breaths, blowing them out through your mouth.
This is so your baby's head can be born slowly and gently, giving the skin and muscles in the area between your vagina and anus the perineum time to stretch. Sometimes your midwife or doctor will suggest an episiotomy to avoid a tear or to speed up delivery. This is a small cut made in your perineum. You'll be given a local anaesthetic injection to numb the area before the cut is made. Once your baby is born, an episiotomy, or any large tears, will be stitched closed.
Find out about your body after the birth , including how to deal with stitches. Once your baby's head is born, most of the hard work is over. The rest of their body is usually born during the next 1 or 2 contractions. You'll usually be able to hold your baby immediately and enjoy some skin-to-skin time together. You can breastfeed your baby as soon as you like. Ideally, your baby will have their 1st feed within 1 hour of birth.

The 3rd stage of labour happens after your baby is born, when your womb contracts and the placenta comes out through your vagina. Your midwife will explain both ways to you while you're still pregnant or during early labour, so you can decide which you would prefer.
There are some situations where physiological management is not advisable. Your midwife or doctor can explain if this is the case for you. Your midwife will give you an injection of oxytocin into your thigh as you give birth, or soon after.
This makes your womb contract. Evidence suggests it's better not to cut the umbilical cord immediately, so your midwife will wait to do this between 1 and 5 minutes after birth. This may be done sooner if there are concerns about you or your baby — for example, if the cord is wound tightly around your baby's neck. Once the placenta has come away from your womb, your midwife pulls the cord — which is attached to the placenta — and pulls the placenta out through your vagina. This usually happens within 30 minutes of your baby being born.
Active management speeds up the delivery of the placenta and lowers your risk of having heavy bleeding after the birth postpartum haemorrhage , but it increases the chance of you feeling and being sick.
It can also make afterpains contraction-like pains after birth worse. Read about preventing heavy bleeding on our page What happens straight after the birth.
The cord is not cut until it has stopped pulsing. This means blood is still passing from the placenta to your baby. This usually takes around 2 to 4 minutes.
