Changes to the Mother
The womb will have been preparing itself for labour for three weeks or so before the contractions of labour start. During this time, the neck of the womb, the cervix, softens and thins out. This allows the contractions of labour to more easily open the neck of womb to allow baby delivery.
It is the baby who decides when labour should start and sends a chemical signal to the tissue of your womb.
