Which sign is typically associated with the onset of labor?

Explanation:
Labor begins when regular, progressively stronger contractions cause the cervix to dilate and efface. That pattern—contractions that come at a regular pace, increase in intensity and duration, and lead to opening and thinning of the cervix—signals true labor. Membrane rupture (water breaking) can occur during labor but isn’t by itself the onset marker, and a bloody show can accompany labor but isn’t sufficient without contractions and cervical change. Slow, irregular contractions that do not bring about dilation are typical of false or prodromal labor, not true labor.
