Your contractions will last from the beginning of labor until the baby is born. The average length of labor and contractions is approximately eight to 14 hours. How long do contractions last, is answered differently with each pregnancy. With your second and third pregnancies, labor and contractions may not last as long.
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). If you're a first-time mum, active labour may take about eight hours.
