The table below summarizes the process of childbirth, from the onset of labor to the delivery of the baby. Cross-references are within this section unless otherwise specified. This is usually identified by one of three events. Contractions of the uterus. Regular, powerful contractions occurring at 10-to 30 minutes intervals.
Contractions feel like cramp pains in the abdomen and lower back.
The cervix dilates gradually with each contraction until it becomes wide enough to allow the baby to emerge. Lower abdominal discomfort and pain. Contractions occur at intervals of 3 to 10 minutes. The second stage of labor begins when the cervix is fully open. The baby normally passes head first through the birth canal.
