This stage continues until your baby passes through the birth canal, vagina, and is born. This stage may last two hours or longer.

You will feel a strong urge to push with your contractions.
Your contractions are likely to happen every three minutes or four minutes and last for between five seconds and 60 seconds. By this time, your cervix will have opened to about 4cm (1.6in).
