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 second stage of labor begins once you are fully dilated to 10 cm. Your provider will let you know that it is time to start pushing your baby out. This stage can be as short as 20 minutes or as long as a few hours.
In the first stage of labor, the cervix will dilate to 10 centimeters (cm) in width. Dilation is typically gradual, but the cervix can widen rapidly over 1 or 2 days. A few different factors can influence how quickly dilation occurs.
In this phase, your cervix will finish effacing and dilate to the full 10 centimeters. This phase may take anywhere from 10 minutes to two 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.
On average, your cervix will dilate at approximately 1 cm an hour. What you can do: Look to your labor partner and health care team for encouragement and support.
The second, pushing phase of labor continues after the cervix is fully dilated (open) to 10 cm until the delivery of your baby. It averages 4 to 8 hours but can be as short as several minutes.
The second stage of labor starts after your cervix has dilated (opened) to 10 centimeters (about 4 inches), and it continues until your baby finishes moving through your vagina and is born. During this time, you will push or bear down (like you do when you have a bowel movement) to help your baby come out.
Doctors have to wait until the cervix is at least 4 centimeters dilated before doing an epidural. Otherwise, the epidural will slow the process down too much. However, once the cervix becomes fully dilated it is too late for an epidural to be given.
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. It's often quicker (around 5 to 12 hours), in a 2nd or 3rd pregnancy.
If you're less than 4 cm dilated: You might be sent home because your labor isn't active enough for hospital admission.
But if you're close to 10 centimeters dilated the research suggests it's not an issue. Evidence suggests it's more of a theoretical fear that just adds additional stress and in some cases results in an epidural (or a higher dose of epidural) to mask that urge.
What to expect: The transition will last about 30 min-2 hrs. Your cervix will fully dilate from 8cm to 10cm. Contractions during this phase will last about 60-90 seconds with a 30 second-2 minute rest in between.
It usually takes from 15 minutes to an hour for the cervix to dilate from 8 to 10 centimeters. Contractions are 2 to 3 minutes apart and last about 1 minute. You may feel pressure on your rectum and your backache may feel worse.
The “push” phase of your delivery depends on many different factors, including what kind of shape you're in, how big the baby is, if you've received an epidural, and so on. Some women push for as long as four hours straight, and some deliver baby on their second push.
"The general progression is about 1cm per hour," says Dr Philippa. "But, as we've seen, things are variable, especially in the early 1st stage before active labour. "Once you are at 10cm dilated, you enter the '2nd stage' of labour, which lasts until the baby is born. This is generally lasts about an hour or 2.
Contractions help push your baby out of your uterus. Your provider may recommend inducing labor if your health or your baby's health is at risk or if you're 2 weeks or more past your due date. For some women, inducing labor is the best way to keep mom and baby healthy. Inducing labor should be for medical reasons only.
"As soon as someone is admitted to the hospital, they're kind of on the clock," Caughey said. -If women aren't too tired, allow them to push at least two hours if they have delivered before, three hours if it's their first baby. They may push longer if they had an epidural as long as the doctor can see progress.
Purple pushing, coached pushing, holding your breath, all mean basically the same thing. Mothers being instructed on pushing causes them to hold their breath and push down into their bottom. Another more normal and less exhausting option would be “breathing or bearing down” working with the contractions.
Joanna was forced to remain in the tilted position 24 hours a day for two and a half months. After 75 days – and what is believed to be the longest labour ever recorded – Joanna gave birth to a healthy girl, Iga, and boy, Ignacy. The two babies were delivered by caesarean at a neo-natal clinic in Wroclaw, Poland.
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).
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.
