  4. 3Pregnancy and parenting stress: including pregnancy and parenting stress. In order to understand the long-term cause-and-effect relationship between stress and anxiety, I further calculate the scores of stress. After making the women’s real pregnancy and parenting stress divided by the total score of the scale, I gain the percentage and then know the degree of stress in three trimesters and after delivery
