The purpose of this study is to evaluate whether perineal massage during labor can help prevent perineal trauma, such as lacerations or episiotomies. The study will test two hypotheses: Null hypothesis: Perineal massage during labor does not prevent perineal trauma. Alternative hypothesis: Perineal massage during labor helps prevent perineal trauma. Participants will be randomly assigned to one of two groups: Perineal massage group: Participants will receive perineal massage during labor. Control group: Participants will receive the standard care provided by the labor and delivery unit. A randomization process will be used to assign participants to each group.
