Due date dilemma

Megan • Prek teacher. Mother of 4. Married. Bilingual. Love to bake. FB. Pinterest.
According to my LMP my due date would be 3/20. My period were never regular. I've had 3 ultrasounds and each ultrasound the baby has measured to be a week ahead and due on 3/13. Which would you go by?
