lightening

The sense of relief felt, during the last three or four weeks of pregnancy, with the descent of the presenting part of the fetus, usually the head, more deeply into the pelvis so that the womb occupies a smaller volume of the abdomen. This reduces abdominal distention and occasions some easing of breathing and general discomfort. Lightening is usual in first pregnancies but may not be apparent later.
