Stages of Labor (See also “Labor”)
- The four stages of labor. The first stage, usually the longest, begins when the cervic starts to open, and ends when it’s completely open (dilated). Blood-tinged mucus is passed from the vagina. Near the end of this stage, contractions become longer and stronger. The second stage involves the actual birth of the baby, and may last as long as three hours - especially during a first birth. The third stage begins when the baby is born, and ends after the expulsion of the placenta. Contractions continue into the third stage. The fourth stage lasts approximately 15 minutes, and includes temporary bodily changes after delivery.
