The method is for monitoring a childbirth process of a pregnant woman. In a measuring step, a lactate concentration of vaginal fluids is measured. In a comparison step, it is determined if the measured lactate concentration is greater than a predetermined lactate concentration that indicates that amniotic fluid has passed from an amnion of the pregnant woman. In a measuring step, the lactate concentration is measured. In a comparison step, it is determined if the measured lactate concentration is greater than a lactate threshold interval. When the lactate concentration is less than the lactate threshold interval the pregnant woman is stimulated in a stimulating step to give birth.
