Summary

This study tests whether using a breast pump for nipple stimulation can safely start labor in pregnant women. The gentle suction may trigger the body's own oxytocin to encourage contractions. Researchers will measure total labor time and compare it to standard methods. The goal is to give patients more control and possibly shorten delivery.
