How can I change the due date on GLOW

Nadia • This angle literally saved my life, it’s a story out of the movies!

I thought I was 7 weeks and 1 day pregnant, however when I went for my first sonogram today, my baby measured at 7 weeks and 5 days. How can I change the due date on GLOW. Because instead of my August 21st due date, it’s now August 16th.
