At this point, your cervix will be dilated 3 to 10 centimeters. (Dilating one centimeter an hour is textbook, but like in early labor, it's different for everyone.)
Once your cervix is 100 percent effaced and 10 cm dilated, you're ready to start pushing your baby out into the world.
Early phase: The cervix will dilate from 1 cm to 3 cm with mild contractions. Active phase: The cervix expands from 4 cm to 7 cm and contractions become more intense and regular. Transition phase: The cervix dilates to 10 cm. Transition ends when the cervix has reached 10 cm and is fully dilated.
Dilating to 1 centimeter does not necessarily mean that labor is only hours or days away. The cervix can be dilated to 1 centimeter for weeks before the beginning of labor. This extent of dilation only signals that the cervix is starting to prepare for labor.

Unfortunately, there's no “normal” when it comes to predicting labor based on dilation or effacement; if you've started, it could be hours or weeks before labor starts. But even if you're not dilated at all, you could still go into labor tomorrow.
(Some OBs will go ahead and break your water at 3 or 4 centimeters.) The reasoning behind this: “Artificial rupture of membranes” (popping a hole in the amniotic sac) will usually jumpstart labor by getting serious contractions underway.
In some women, the foetal head is not in the right position and doesn t apply aptly to the cervix, which is why the cervix doesn t open. This can lead to difficulty in dilation.
Getting up and moving around may help speed dilation by increasing blood flow. Walking around the room, doing simple movements in bed or chair, or even changing positions may encourage dilation. This is because the weight of the baby applies pressure to the cervix.
If you're less than 4 cm dilated: You might be sent home because your labor isn't active enough for hospital admission.
Based on the timing of your contractions and other signs, your doctor or midwife will tell you to head to the hospital for active labor. This phase typically lasts from three to five hours and continues from the time your cervix is 3 cm until it is dilated to 7 cm.
The cervix generally needs to be dilated to 10 centimeters before it's ready for the baby to pass through. Your cervix can be dilated to a couple of centimeters for a few weeks before delivery. This softening can cause the mucus plug to be dislodged and come out.
Early dilation often feels like menstrual cramps as the cervical changes cause pain and cramping noticed in the lower part of the uterus. It is the same sensation and location as menstrual cramps.
Dilation is checked during a pelvic exam and measured in centimeters (cm), from 0 cm (no dilation) to 10 cm (fully dilated). Typically, if you're 4 cm dilated, you're in the active stage of labor; if you're fully dilated, you're ready to start pushing.
As the baby's head drops down into the pelvis, it pushes against the cervix. This causes the cervix to relax and thin out, or efface. During pregnancy, your cervix has been closed and protected by a plug of mucus. When the cervix effaces, the mucus plug comes loose and passes out of the vagina.
Inducing labor before 39 weeks of pregnancy is recommended only if there are health problems that affect you and your baby.
Supported squat
Try to achieve a deep squat with your legs in a “V” position. This position can really help to open up your pelvis, move your baby down, which can also help to dilate your cervix.
Your cervix needs to open about 10cm for your baby to pass through it. This is what's called being fully dilated. In a 1st pregnancy, the time from the start of established labour to being fully dilated is usually 8 to 18 hours.
massage around the neck of your womb if it is soft but closed — this 'stretch' can stimulate your body to release prostaglandins, which encourage the cervix to open.
It is not uncommon for the cervical ripening to take up to 24-36 hours!! It is also not uncommon to use different techniques to ripen the cervix. You may feel contractions during this process. If the contractions become painful, you will be able to request medication to relieve your discomfort.
Spending most of your time in bed, especially lying on your back, or sitting up at a small angle, interferes with labor progress: Gravity works against you, and the baby might be more likely to settle into a posterior position. Pain might increase, especially back pain.
What If My Cervix Doesn't Open? Your doctor or midwife may check for cervical dilation and effacement during your late third-trimester prenatal appointments. The changes usually begin several weeks before delivery, but it's not uncommon to still have a closed cervix near your due date.
