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.
But just being dilated doesn't mean labor is definitely around the corner. You could be four centimeters dilated, and stay that way for weeks—or your cervix could be completely closed and you could find yourself in active labor hours later. Again, it's just a measure of progress.
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.
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.
(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.
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.
If you're less than 4 cm dilated: You might be sent home because your labor isn't active enough for hospital admission.
It is very common if you have had a vaginal delivery before as the uterus is not as firm and there is less pressure pushing the baby into the birth canal before the onset of labour. As well a baby's head can be engaged one day and not the next, especially if you have had a vaginal delivery before.
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.
“I've seen patients become dilated about 3 or 4 centimeters without active labor,” says Williams. “They're usually in their late third trimesters.” On the flip side, it's also normal for the cervix not to be dilated at all before labor.
Labor pain may radiate around your abdomen, back, and thighs. Your cervix is also dilated around 4 to 7 centimeters. Someone who has never given birth before may be in active labor for around three to six hours; a person who's done it before might take one to three hours.
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.

The American College of Obstetricians and Gynecologists (ACOG) said active labor for most women does not occur until 5 to 6 cm dilation, according to the association's guidelines.
You can walk around with dilation of four or even five centimeters, but without regular contractions, you're not in labor. But don't worry. Whether you dilate a little, a lot, or not at all, baby's on their way.
Additionally, some hospitals will admit you if you are dilated four of five centimeters and are having regular, strong contractions—especially if it is not your first baby or you have a history of fast labors.
Checking for dilation does not induce labor unless the exam is used in conjunction with one or more common labor induction methods. A common intervention that may be offered during a cervical exam is called a “membrane sweep,” which is a procedure that can be performed if you are at least one centimeter dilated.
Many of these symptoms are due to increased levels of the hormones estrogen and progesterone, which boost blood flow throughout your body to support your baby — including to your labia. As a result, your labia and vagina may experience the following changes: Swelling.
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.
In most cases, however, an epidural will not be given until the mother is at least 3-4 centimeters dilated. Once the mother is fully dilated most doctors and hospitals will consider it too late for an epidural to be given.
