True labor contractions last more than 30 seconds at the onset and get progressively longer, up to 60 seconds, whereas false labor contractions vary in length and intensity.
This stage continues until your baby passes through the birth canal, vagina, and is born. This stage may last two hours or longer. Contractions may feel different from the first stage of labor -- they will slow to 2 to 5 minutes apart and last from about 60 to 90 seconds. You will feel a strong urge to push with your contractions. Try to rest as much as possible between intervals of pushing, and only push when the health care provider tells you.
