During the first stage of labor, your cervix will start to open (dilate) and thin out (efface) to allow your baby to move through your birth canal. Dilation starts at 1 centimeter (less than 1/2 inch) and goes all the way to 10 centimeters before there's enough space to push your baby into the world.
The time between dilating to 1 cm and giving birth varies from woman to woman. One woman may go from having a closed cervix to giving birth in a matter of hours, while another is 1–2 cm dilated for days or weeks. Some women do not experience any dilation until they go into active labor.
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.
Stage 1: Early and Active Labor
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.
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. Active labor tends to be felt in a larger area but can be a similar sensation as cramping (with more intensity of course).
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.

Try being upright
One of your biggest allies is gravity. When you are upright—standing, sitting or kneeling—the weight of your baby presses on the cervix, encouraging it to open. An upright position may also help get your baby into the best position for birth.
It may be hard to talk or move easily. 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.) If you're opting for an epidural, the time is…now!
If your water (aka “amniotic sac,” “bag of waters” or “membranes”) hasn't broken on its own when you arrive at the hospital, and you're five or more centimeters dilated, your OB might recommend bursting the bag by hand—especially if your cervix seems to be making slow (or no) progress.
Yep easily at a 1cm. Hi, I did!! Slightly different as I was being induced. So after 3 lots of pessary I was only 1cm dialated.
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 labour, the time from the start of established labour to being fully dilated is usually 8 to 12 hours. It's often quicker (around 5 hours), in a 2nd or 3rd pregnancy.
Check for dilation.
Try to insert the tips of your fingers into your cervix. If one fingertip fits through your cervix, you're considered one centimeter dilated. If two fit, you're two centimeters dilated. If there's additional space in the opening, try to estimate how many fingertips would fit to determine dilation.
Can you feel your cervix dilating? As your cervix starts to thin and soften, you may or may not notice twinges and sensations in that area of your pelvis. This can be as much you trying to convince yourself something is happening though!
Toward the end of pregnancy, vaginal tissue becomes more sensitive, so a cervical exam (which is not known for being gentle) can feel uncomfortable or even painful.
As cervical dilation increased, there were significant increases in self-reported pain and observed pain on all the cited measures. Pain was characterized as 'discomforting' during early dilation and as 'distressing, horrible, excruciating' as dilation progressed.
Theoretically, the unequal walking pattern created by the curb causes the pelvis to open and allows the baby's head to descend. When the baby's head is deeper into the pelvis, there is more pressure on the cervix, causing dilation and effacement. This uneven walk should be done for about 10 minutes.
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.
Medical cervical ripening
Medications also can be given to help induce softening and dilatation of the cervix. Oral or vaginal suppository drugs, such as misoprostol and other prostaglandins, are also commonly used to ripen the cervix.
Active labor usually lasts about 4 to 8 hours. It starts when your contractions are regular and your cervix has dilated to 6 centimeters. In active labor: Your contractions get stronger, longer and more painful.
According to Brichter, sitting on an exercise or birthing ball in neutral wide-legged positions prepares the body for labor by increasing blood flow, opening the pelvis, and encouraging cervical dilation. You can also try birth ball exercises such as circular hip rotations, rocking, and gentle bouncing.
If you're more than 4 cm dilated: You'll be admitted to the hospital to continue your labor and delivery.
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.
