A self-check of the cervix is not a substitute for a cervical exam by a healthcare professional, however. In some cases, a doctor may recommend a transvaginal ultrasound to measure cervical thickness and length, as this method is likely more accurate. The amount of time it takes for complete cervical effacement during labor varies greatly. For others, cervical effacement may occur slowly over several weeks.
The same applies to dilation. It is not uncommon for a woman to be 1—2 cm dilated a couple of weeks before going into labor. Although they may occur at different speeds, cervical effacement and dilation can go hand in hand.
The researchers analyzed how fast effacement occurred in relation to dilation. Cervical effacement can start a few weeks before labor.
The length and thickness of the cervix at different stages of pregnancy can also provide useful insight for healthcare providers. For example, the length of the cervix at mid-pregnancy may give a clue as to pregnancy duration.
A pregnancy longer than 41 weeks can raise the risk of complications for both the woman and the fetus. Assessing which women have a high risk of a prolonged pregnancy allows healthcare providers to determine the necessity of labor induction. Cervical effacement refers to the stretching, thinning, and shortening of the cervix in preparation for vaginal childbirth.
Along with effacement, cervical dilation must also occur to allow vaginal delivery. Typically, healthcare providers measure effacement in percentages or by the length of the cervix that remains. Symptoms such as the loss of the mucus plug and pelvic pain may indicate that cervical effacement has begun. The rate of complete effacement varies from woman to woman. In this article, we provide a guide…. Membrane stripping is a method of inducing labor.

Doctors also advise that women not have sex after their water breaks to avoid introducing any bacteria into the uterus. Your practitioner will want you to have your baby within a day or two after your water breaks. If you are close to your due date, your water breaks, and you don't go into labor on your own within a relatively short period of time, you will need to have labor induced.
If your labor doesn't begin within a specific time period, your physician may want to bring on induce labor. How long your health practitioner is comfortable waiting before inducing will depend on your individual situation.

Contractions are strong, rhythmic, regular cramps that feel like a bad backache or extreme menstrual pain. These little doozies, if they're the real thing, are the most reliable of all the signs and officially mark the onset of labor. A contraction occurs when your uterus tightens and then relaxes.
Real contractions usually start in the back of your body and move toward the front. These movements open the cervix and help push the baby into the birth canal. True contractions come closer and closer together in a predictable pattern and last around 30 to 70 seconds each. They get steadily stronger and keep coming, regardless of what you do.
You and your health practitioner should come up with a game plan ahead of time about when you should call and what you should do if you suspect you're in labor.
Most practitioners will probably tell you to call when you have contractions that last for around one minute and occur every five minutes for about an hour, but this could vary greatly depending on your health history and past pregnancy record. Women who have given birth before may have a quicker labor the second or third time around, so it's important not to wait too long to call if you think things might go quickly. Be sure to discuss this with your doctor or midwife.
To time the frequency of contractions, start at the beginning of one and count until the beginning of the next one. When in doubt, call your practitioner.

Your doctor or midwife can give you concrete advice and help you determine if this is the moment you've been waiting for. American Pregnancy Association. Signs of Labor, Mayo Clinic.
Contractions shorten or thin the cervix. This process is called effacement and is measured in percentages. Your cervix starts out three to four centimeters long. When it is 50 percent effaced, it is about two centimeters long. When it is percent effaced, it is "paper-thin. Effacement can happen over days before labor starts.
Or, it can happen over hours as labor progresses. With a first labor, it can take quite a while for the cervix to completely efface. Labor may start slowly because the cervix first thins and then dilates. Dilation is measured in centimeters, one to In general, early labor moves to active labor by about six centimeters cm. During active labor, contractions are more regular and intense, and cervical change is more regular.
Active labor, however, requires more coping skills. When contractions become longer, stronger, and closer together, the key to coping is to relax between the contractions. During the contractions do whatever technique helps you deal with them. The last two centimeters of dilation are called transition because it is the transition between the first and second stage of labor.
This is the time that contractions are the most intense. The first stage of labor ends when the cervix is fully dilated and your baby's head slips through your cervix. It is more difficult than the distance suggests because your baby must turn to fit through your pelvis. Cervix thins and dilates during labor.
