What does the cervix do?
The cervix is an important part of the reproductive system. During your pregnancy, the cervix is responsible for keeping the baby inside until it’s time to make an appearance.
Many women assume that the cervix only changes during pregnancy, but that’s not true. The cervix actually changes very often. During the menstrual cycle, the cervix opens and is lower. This allows blood to leave the area, being your period.
During the time of ovulation, the cervix rises. This gives the body a higher chance of conception. As you progress through pregnancy, the cervix usually lowers and softens. This makes it easier for the baby to travel down the birth canal when it’s time to be born.
When labor begins, the body prepares for childbirth, and the cervix dilates. This allows the baby to be born safely. The cervix can expand to around 10cm to allow the baby’s head to appear.
What happens if I have an open cervix during pregnancy?
For most women, the cervix will close during pregnancy, but some women can experience an open cervix. This would need to be monitored throughout pregnancy to reduce the risk of early labor. It may require a cervical cerclage, whereby the cervix is closed through a stitch.
An open cervix can increase the risk of premature birth or miscarriage, but it is difficult to diagnose.
When does the cervix start to dilate?
The cervix can start dilating at any time. Some women find that their cervix is dilating a couple of months before their due date. During your appointments, your cervix may be assessed to monitor the dilation process.
Your cervix may be dilating for a longer period of time if you are experiencing a second pregnancy. There’s no way of knowing how long it will take you to dilate, as every pregnant woman is different. You might also be wondering – can your water break without being dilated? And the answer is yes!
After 37 weeks of pregnancy, you may notice that your mucus plug has been released. This is a sign that your pregnancy is progressing for labor.
Reasons for cervix not dilating before labor process
We can understand you wondering, why won’t my cervix dilate? At the end of the day, no one really talks about these things!
There could be many reasons why your cervix is not dilating. If you’re still earlier in the pregnancy, then you really don’t need to worry. Here are some common reasons for the cervix not dilating.
First pregnancy
Pregnancy is just as new to your body as it is to your mind! This means your body is trying to learn the best actions to carry and deliver the baby safely. While some women may start dilating weeks before, others may remain completely closed until the labor actually begins.
Prodromal labour
This is when labor begins and ends before active labor actually starts! It is often referred to as false labour. Prodromal labour happens for a number of reasons, such as your baby’s position, your pelvic shape and position or stress. Many of these factors are out of your control.
Sometimes actions can be taken to change your baby’s position. For example, an ECV may be offered if your baby is breech. These actions do not always work, and it’s your choice whether you have them.
Due date
You aren’t really meant to start dilating until closer to your due date, so maybe that’s the reason you aren’t! If your due date passes, it will normally be another two weeks before you have an induction. This means you could reach the 42nd week of pregnancy. So try not to worry if you aren’t dilating before reaching 37 weeks pregnant.
Your cervix and dilation will be closely monitored during pregnancy, so try to relax. If there are complications, you will be told. Medical professionals can offer the most valuable advice.
Reasons for cervix not dilating in labor
Is your latent labor stage taking a long time? It definitely can do. You may be experiencing some labor contractions, or your water may have broken. So, why are you experiencing prolonged labour?
Your position
It might seem silly to think that your position can affect your dilation, but it’s true. If your labor begins at night time, it’s a good idea to try and rest if you can. The extra sleep can give you more energy when it’s time to start pushing.
If your labor begins in the daytime, you can encourage the labor by staying in an upright position. This makes it easier for the baby to move and the cervix to dilate. When in active labor, take some time to find the best position for you.
Mother’s pelvis shape
There are four pelvis shapes that you may have. This is out of your control, but some shapes can make dilation easier.
Baby’s position
Some babies don’t move into the ideal birthing position. Doctors may suggest some methods to achieve this, but they may not always work. They may also suggest a c-section rather than a vaginal birth.
Try not to worry, regular cervical exams and ultrasound scans in pregnancy will give you insight into your baby’s position. Sometimes certain risk factors can change a birthing plan, such as complications with the umbilical cord.
Stress
If you’re feeling nervous and stressed, your body may not continue to prepare for birth. You should try to remain calm during labor, but we know this can be hard. We recommend choosing a birthing partner who has a calming presence. This will really help you to relax. Your doctor may suggest an epidural if you are struggling with labor pain.
While some of these are out of your control, you may find some things could help, such as:
- Changing positions
- Having a short walk
- Asking your birthing partner for a massage
While in labour, the medical team will continue monitoring your cervical dilation. They will also be looking out for regular contractions.
What is it called when your cervix won’t dilate?
If you’re in labor and your cervix won’t dilate, it may be referred to as failure to progress or prolonged labor. Various actions can be taken to get your labor moving. Your doctor will be able to advise you on the most appropriate methods.
Cervix not dilating after induction – Why?
An induction is typically completed if you reach the 42-week mark or your baby’s safety is at risk. There are a few methods that may be used, including:
- A membrane sweep
- Application of gel to the cervix
- Rupturing the membrane by manually breaking your waters (you may feel pressure when your water breaks)
- A hormone may be given to encourage uterine contractions
It is rare that an induction will not help the labor to progress. However, if this happens, the midwife or doctor may suggest you have a c-section instead. This involves a surgical cut being made across the stomach. C-sections are often used when a vaginal delivery is not the safest option. Some women plan to have a c-section in the first instance. This should be discussed with a doctor so that you are aware of any risks.
If your cervix isn’t dilating after induction, try not to worry. You’re in the right place, and the healthcare professionals will assist you with the birth.
Can you be in labor and not dilate?
Established labour typically begins when you are at 4cm dilated. This is because the cervix is preparing to soften and shorten to allow the baby to arrive. In the latent phase of labor, dilation can begin and take a while to progress.
After the first stage, you are in the active phase, and you will likely experience more frequent contractions. During the second stage of labor your cervical dilation will increase from 4cm to 7cm. During the third stage, the cervix dilates from 7cm to around 10cm; this means you are fully dilated. After the delivery of the baby, you will birth the placenta.
Just because you have reached 10cm does not mean the baby’s arrival is imminent. It could still take a while for the baby to travel down the birth canal and be delivered. Your progress will be monitored closely so that stronger contractions can be identified.
Whether you’re several weeks off your due date or in the first stages of labor, try not to worry about dilation. No one can predict how long it will take for you to fully dilate. Make sure to let your midwife know; they can give you the most accurate advice.
Enjoy the rest of your pregnancy, and get ready for your little one to arrive! This is such an exciting time for you, and we wish you the best with your labor and delivery.
