Prostaglandin theory
This theory is said to be the pressure on the cervix stimulates the hypothesis to release oxytocin from the maternal posterior pituitary gland, the presence of this hormone causes initiation of smooth muscle contraction of the body.
Oxytocin theory
This theory is compared to a balloon of which if the point is met it will burst does labor process occurs.

Pre monitoring signs of labor
Provides relief from diaphragmatic pressure and shortest of breathe or lightening her load; approximately 10 to 14 days before labor begins
