Contraction: This usually has to do with the onset of labor. It is a muscular tightening of the uterus. Contractions are timed from beginning to end of hardening of the uterus (duration) and from beginning of one contraction until the beginning of the next (frequency). A third descriptor is intensity or how hard or painful the contraction.
