How long does it take for the cervix to open after it flattens?

For the vast majority of pregnant women who choose normal vaginal delivery, before officially delivering the baby, they must wait for the cervix to open to a certain degree of width, about ten finger widths, to allow the baby to pass through smoothly. Cervical dilation is a condition that occurs before the cervix dilates. Some pregnant mothers asked the editor about this: How long does it usually take for the cervix to dilate after the cervix dilates?

How long does it take for the cervix to open after dilation?

For first-time mothers, the cervix will open first and then the cervix will dilate, which usually takes about eight hours. However, because each pregnant woman's body size and physical fitness are different, the time required for the cervix to expand will also vary. For primiparas, cervical dilation usually occurs at the same time as cervical opening, so the time required is relatively short.

Before the cervix opens, pregnant women will first experience three prenatal signs: spotting, pain, and rupture of amniotic fluid. Before giving birth, a small amount of blood will be discharged from the pregnant woman's vagina, followed by another antenatal pain. This is caused by the continuous contraction of the uterus, and the pain will become more regular as the time interval between pains gradually decreases.

The strong contraction of the uterus will cause the pressure inside the uterus to continue to increase, causing the cervix to be further enlarged due to the pressure, and the amniotic fluid will rupture as the fetal head descends. At this time, you will see signs of amniotic fluid rupture. Once amniotic fluid ruptures, it proves that the baby is about to be born. The pregnant woman should go to the hospital immediately to wait for the cervix to dilate for delivery.

How long does it usually take for the cervix to dilate before giving birth?

After the pregnant woman's cervix dilates, it may take another 8 or 9 hours before delivery. When a woman chooses to give birth naturally, the cervix usually opens first, and then the cervix dilates. It usually takes more than eight hours, but the situation of each pregnant woman is different.

Before a woman gives birth naturally, she will experience many labor symptoms, such as uterine contractions. After the pregnant woman's upper cervical canal gradually expands, uterine contractions will intensify to a certain extent. It does not mean that delivery will occur immediately once the cervix dilates. The cervix must also dilate to a certain extent. The cervix is ​​considered fully dilated when it gradually expands to 10 centimeters. Only after the cervix is ​​completely opened can the second stage of labor begin, at which point the pregnant woman can push hard to give birth.

The dilation of a woman's cervix cannot exceed 2 hours, so pregnant women need these 2 hours to give birth. If it takes more than 2 hours, it means the delivery process is not complete and the doctor will take other measures. It usually takes 8 hours from the time the pregnant woman's cervix opens to the start of delivery.
