The cervix is a channel that normally remains closed during pregnancy, eventually becoming shorter and opening at the time of delivery.
The examination of the cervix is performed either with an ultrasound scan or a vaginal examination performed by the midwife or physician.
The examination of the cervix makes it possible to assess how close the birth is.
This procedure can be uncomfortable or even painful; if that is the case, do not hesitate to communicate this to the person who is examining you.
