Introduction
Most pregnant women experience a sensation of tightness or hardness in their abdomen during the late stages of pregnancy. Some women may notice this sensation at any point throughout their pregnancy. For most healthy expectant mothers, abdominal tightening in the third trimester is entirely normal and results from uterine contractions. However, expectant mothers should still pay attention to these “Braxton Hicks” (false) contractions.
Most pregnant women experience tightening or hardening of the abdomen during the late stages of pregnancy. Some women may notice this sensation at any point throughout their pregnancy. For most healthy expectant mothers, abdominal tightening in the third trimester is entirely normal and results from uterine contractions. Typically, these episodes are painless or cause only mild, menstrual-like cramping, lasting less than one minute each. They often occur more frequently after physical exertion.
This occurs because, as pregnancy progresses into its final weeks, the uterus becomes increasingly sensitive and may contract in response to various stimuli. These contractions—termed “Braxton Hicks” or “practice” contractions—differ from true labor contractions in that they do not lead to preterm delivery. Nevertheless, expectant mothers should still pay attention to them: upon noticing abdominal tightening, they should immediately stop whatever activity they are engaged in and rest. If such contractions occur while walking, they should pause until symptoms subside before continuing. Only when contractions occurring at or near the due date are accompanied by pain do they signal the onset of labor. Furthermore, if vaginal spotting (“show”) or rupture of membranes (“water breaking”) accompanies these painful contractions—and false labor has been ruled out—delivery is likely imminent.
