In transitional labor, contractions become extremely intense, coming every 2-3 minutes and lasting 60-90 seconds, with little to no break in between. The birthing person may feel overwhelmed, restless, or irritable, often vocalizing more or needing to move around, and may express feelings of uncertainty or fear. Physical signs include shaking, nausea, and a strong urge to push, signaling that the baby is close to being born.
