Why does the cervix not open?

In the late stages of pregnancy, a series of changes will occur in the pregnant woman's body. As the uterine contractions gradually appear, the pregnant woman's uterus will continue to open, allowing for a smooth delivery. However, some pregnant women may find that their cervix is ​​not dilated during physical examinations. They are worried that this abnormality may affect their normal fertility. So, why does the cervix never open? Let’s take a look at the reasons below.

1. Opening of the fingers = opening of the cervix

Dilation of the cervix, also known as cervical dilation. Under normal circumstances, the cervix is ​​open to about the distance of a fingertip. As labor progresses, the cervix gradually expands until it opens to allow a normal-sized fetus to pass through, that is, to a diameter of 10 cm. The whole process is called cervical dilation.

2. Open your fingers = have a baby

The whole process of delivery is divided into 3 stages, also known as 3 stages of labor. The first stage of labor is the period of cervical dilation; the second stage of labor is the period of fetal delivery; the third stage of labor is the period of placental delivery, which refers to the process from fetal delivery to placental expulsion.

The size of the cervix opening has a lot to do with when the baby is born. When the cervix is ​​dilated to the size of one finger, it means that the expectant mother is in a state of labor, but has not actually given birth yet. Pay attention to changes in fetal movement and go to the hospital for treatment at any time if there are any abnormalities. Generally speaking, when the cervix is ​​3 fingers dilated, the expectant mother can enter the delivery room; it usually takes a long time from 3 fingers dilated to full dilation; when the cervix is ​​10 fingers dilated, the expectant mother has entered the rhythm of giving birth, so keep working hard!

When does the palace open?

The process of cervical dilation is relatively slow. Usually, the cervix gradually flattens in the second week after the 9th month of pregnancy, which is also the process of cervical formation. Your cervix will dilate to 10 centimeters when your baby is born. It will be slow at first, and it takes an average of 8 hours from labor to 3 centimeters of dilation, and an average of 4 hours from 3 centimeters of dilation to 10 centimeters.

Generally speaking, medication for pain will not be used until the cervix is ​​dilated to 3 cm. This indicates that the mother has entered the active phase of labor. The cervix has dilated to 3 cm, the cervix has become soft, thin, and elastic, and the interval between each contraction is 2-3 cm. After delivery, the cervix will gradually dilate with regular uterine contractions.

What to do if the cervix is ​​not open

1: Delivery is carried out according to specific circumstances: Due to the influence of hormones, the cervix gradually softens, and the pressure of the fetal head causes the mother's cervix to expand. However, the mother's physical condition and mood will affect the opening and closing of the cervix. The most important thing is that mothers should understand that intense labor pains and the opening and closing of the uterus are complementary to each other.

2. The cervix opens but the contractions are weak: If the contractions become stronger but the cervix does not open, the fetus will not be born. Only when both aspects are carried out simultaneously can the birth of the fetus be promoted. Muscle tension can cause muscles to become stiff. The simplest example is when you clench your fist, your palm becomes hard, and when you unclench your fist, your palm becomes soft. By the same token, if you keep your mood good and your body relaxed, the cervix will open more easily.
