Definitions for "Contractions"
Regular tightening of womb muscles in preparation for delivery.
The muscles of the uterus contract to open up the cervix when the baby is ready to be born. These tightenings are called contractions and are felt as pains that come and go at regular intervals. They may feel like period pains, backache, or as strong pulling pains low down at the front of the bump.
The regular tightening of the uterine muscles as they work to dilate the cervix in labour and push the baby down the birth canal.
