Types? Do you mean stages? If you mean stages, its first, second, and third. First stage is early labor, second stage is active labor (the stage where the baby comes out) and third stage is when the placenta is delivered. Then there's false labor, which can seem like early labor but fizzles out before it progresses into anything.
3rd stage of labor is complete cervical dilation and delivery of the baby.
