How long does it take for the cervical canal to be 19mm long

The length of the cervical canal is 19 mm. This situation may be a sign of imminent birth. Generally speaking, the length of the cervical canal under normal conditions is about 2.5~3.0. If the cervical canal becomes shorter and gradually disappears, then this situation may be about to give birth. Generally, 19 mm cannot be determined how long it will take to give birth, but there is the possibility of giving birth at any time. Therefore, we must pay attention to it and observe our own body changes in time to see if there are any signs of giving birth. Pay attention to maintaining a good mentality before giving birth. You can move more in the later stages of pregnancy, climb stairs, or walk around more.
