The experimental group. In the active phase of the labor (cervical dilatation = 5 cm), the peanut ball, which has a cover provided by the researcher and changed in each patient, will be placed between the knees of the participant for at least 30 minutes every hour, and a position change will be provided with the peanut ball in each time. The positions to be given with the peanut ball, semi sitting lunge, side lying, tucked, leaning forward, pushing and sitting position.

Standard care will be given to the control group without positioning with a peanut ball.

The experimental group will be positioned with the peanut ball until the end of the active phase of labor.

The primary outcome measure is the length of first stage (active phase) and second stage of labor in obese pregnant women.

Visual Analog Scale (VAS) is used to convert some values that cannot be measured numerically. Two end definitions of the parameter to be evaluated are written at the two ends of a 10 cm line, and the patient is asked to indicate where on this line their situation is appropriate by drawing a line or by placing a dot or pointing. For example, for pain, I have no pain at one end and very severe pain at the other end and the patient marks his/her current state on this line. The length of the distance from the point where there is no pain to the point marked by the patient indicates the patient's pain (0: no pain 10: severe pain)
