weeën

Weeën is a Dutch term most commonly used in obstetrics to describe the rhythmic contractions of the uterus during late pregnancy that signal the onset and progression of labor. The plural form weeën refers to multiple such contractions. In everyday language the word can also denote brief pains or twinges, but in contemporary medical and lay contexts the obstetric sense is primary.

During labor, weeën are regular, involuntary muscular contractions of the uterus that help to dilate and efface the cervix and to push the fetus downward. Early contractions are usually milder and spaced apart, while as labor progresses they become stronger, longer and more frequent. Braxton Hicks contractions, often called voorweeën, may occur before true labor; those are typically irregular and do not cause progressive cervical change. True weeën, by contrast, become regular and rhythmic and increase in intensity over time.

Contraction patterns are commonly described by frequency (how often they occur), duration (how long each contraction lasts) and intensity. In many pregnancies, the transition from latent to active labor includes a noticeable increase in regularity and strength, with cervical dilation proceeding toward 10 centimeters. The exact timing and progression vary between individuals and pregnancies.

Medical guidance is advised if contractions become regular and progressively stronger, if the membranes rupture, or if there is vaginal bleeding or reduced fetal movement. In such cases, contacting a healthcare professional or seeking evaluation is recommended.
