Baby measuring a week ahead

Dana ☀️ • 32. Married 7.12.13 • Mommy to Elliott 👧🏼 3.5.16. Due with baby girl #2 12.12.18
I was told at my appointment today that the baby is measuring a week bigger than she should be.  I am currently 23 weeks.  Did anyone else experience this.  Was your baby large when they were born?
