Uterine contraction



Tightening of the uterus that occurs on and off during pregnancy and becomes more regular, closer together and stronger during labor.


A warm bath, gentle motion from a rocking chair or deep breaths through the contractions can help control pain. Birthing classes also may offer tips.
