How to Check Cervix for Dilation

Last Updated on

When your due date of delivery approaches, you will feel contractions. These contractions are nothing but the tightening of the uterus and dilation of the cervix. The dilation of cervix makes it possible for the baby to move from the uterus to the vaginal canal. The cervix plays an important role in a woman’s body during the process of childbirth. The cervix dilates from 1 centimetre to 10 centimetres before a woman goes into active labour. Therefore, to know if you are ready to give birth or not, you must check your cervix for dilation.

Why Should You Check Your Cervix for Dilation?

It is beneficial to know your body when you are going through the life-altering process that is pregnancy. It will help you determine what stage of labour you are in and whether the baby is ready to come out. Checking your cervix for dilation will let you know if you can begin to push the baby out. However, if you are not confident or unsure of doing so, it is best to avoid it.

Checking your own cervix for dilation can help you in the following ways:

  • It gives you control over your body during labour, which is an emotionally and physically intense situation for a woman.
  • Relying on lab tests can be time-consuming and you will have to wait for the results. Checking your own cervix for dilation will let you know the results immediately.
  • Checking whether your cervix is dilated well will prepare you for the final stages of labour.
  • You know your body better than anyone else, so you can do these tests at home without the risk of infections due to external equipment and so on.

Steps to Check Your Cervix for Dilation

Checking your cervix for dilation is important to be aware of the stages of labour. Before you go into the details of the process, it is important to be prepared to keep your cervix free from infections. Here are the basic preparations you need to do before checking your cervix for dilation:

Preparation to Check Your Cervix for Dilation

Here is how can you can prepare to check your cervix for dilation at home:

1. Clean Your Hands Thoroughly

Your hands should be washed thoroughly and disinfected to ensure that there are no germs that enter your uterus and cause infections when you check it for dilation. Use a good hand sanitiser on your hands. Ensure that your fingers and fingernails are well-maintained to avoid internal cuts and bruises and infections.

2. Take Advice From Medical Professionals

To make sure you and your baby are healthy, it is important that you talk to your doctor. As the ninth month of your pregnancy approaches, your doctor will look for signs of labour. He may do an exam to see if your cervix has dilated or not and whether the baby has turned head down or not. You should also ask your doctor if you can check your cervix for dilation at home. If he says yes, then you can proceed.

3. Work as a Team With Your Partner

Although your body is going through the rigours of pregnancy, you can involve your partner to help you through this. Having your partner by your side gives you the moral support that you need during labour.

4. Get Comfortable

Get into a comfortable position before you check your cervix for dilation. The most preferred position is to squat with both your legs as much as possible. If possible, you can even sit on the floor with your legs up front and lift one of your legs up on a sofa or an elevated surface.

Now that we have covered the basic preparations for checking your cervix for dilation, let us go through simple steps that you can follow to check the dilation of your cervix in your home.

Checking the Dilation of Your Cervix at Home

You can check the dilation of your cervix at home by performing the following steps:

1. Insert Your Index and Middle Finger in Your Vagina

Ensure that your fingers are clean and sterilised as much as possible using solutions containing over 60% alcohol, like hand sanitisers.  After cleaning, find the opening of your vagina with your fingertips and push the two fingers into your vagina.

2. Push the Fingers Deep to Reach the Cervix

The cervix is located at the end of the birth canal and is the opening of the uterus. Hence, push your fingers in deep to reach the cervix. Make sure not to put pressure or poke to avoid bruises and the breaking of the amniotic sac. Be gentle and probe around with your fingers. A dilated cervix will let you feel the amniotic sac. It will feel like a balloon filled with water. In a cervix fully dilated up to 10 centimetres, you can even feel the baby’s head crowning.

3. Probe Further to Understand the Level of Dilation

If you are able to pass a finger through your cervix, it can be considered as a 1-centimetre dilation. Two fingers imply 2 centimetres dilation and so on.

4. Get Medical Help

A dilation of 3 centimetres or above is a sign of labour. In such a case, it is always advisable to go to a hospital.

Look for These Additional Signs of Cervix Dilation

You can also look for these additional signs that may indicate cervix dilation. However, these are on a case-to-case basis and may not hold true every time.

1. Pay Attention to the Sounds You are Making

At 1-4 centimetres of dilation, it is very easy to make conversation normally. At 4-5 centimetres, it will be nearly impossible for you to talk. At 5-7 centimetres, you will be making very loud noises as the pain increases. At 7-10 centimetres, you will be making louder noises as you reach the ultimate level of your pain and cervical dilation.

2. Scan Your Emotions

At 1-4 centimetres of dilation, you will be elated and laughing at different things. At 4-6 centimetres of dilation, you will be smiling and laughing at small things. At later stages between 6-10 centimetres, you will get irritated even at very small things.

3. Check for Smells of Dilation

Pre-natal scents have a characteristic deep smell. If you notice a stark change to the scent of the room in which the delivery is happening, it is a sign that your cervix has dilated to around 6 to 8 centimetres.

4. See If There is Blood and Mucus

If you see blood and mucus which is of a characteristic brown or pink colour from your vagina, it is a sign that you are about 6 to 8 centimetres dilated.

5. Feeling Nauseated

The feeling that you get that you have to vomit is a characteristic of a 5-centimetre dilation.

6. Curling of Toes

Curling your toes or trying to stand on your toes is a sign of a 6 to 8-centimetre dilation.

When Not to Check Your Cervix During Pregnancy

Checking cervix for dilation should be avoided at all costs in the following scenarios:

  • If a trained medical professional has advised you against it, you should stay away from checking your cervix.
  • If you have had pre-labour or dilation issues in the past, you should avoid checking your cervix.
  • If you have a cervical stitch to avoid miscarriages and pre-term births, you should not do external checks on your cervix.
  • If you have placenta previa, avoid checking your cervix.
  • Do not check your cervix if your water has already broken as you will risk introducing bacteria to your birth canal.

Pregnancy, labour, and finally having a baby in your arms are life-changing experiences that bring you and your partner immense happiness. These tips to check your cervix for dilation can help you be better prepared for labour and delivery.
