Welp this distressed mama

So my obgyn says my baby’s measuring small for the gestation age (I am 36 weeks pregnant)! And I made my anxiety worst by goggling about this. But I too feel I am carrying very small at 36 weeks. This is my 2nd child and I know you shouldn’t compare but I am definitely carrying smaller then my 1st pregnancy. I also know everyone carries different and all that but I am still worried. This mom isn’t thinking straight.

I have another growth scan scheduled for 37 weeks and this made me worried more. Pl help ease my mind with similar issue and how the baby turned out. Does the due date pushed back if the baby’s measuring small?

This pictures is 36 weeks 4 days belly.
