Changing the due date in the app?

Gina • Ttc baby #1!
I have a long luteal phase so it kinda threw the <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> off while I was ttc. I am happy to say my husband and I are expecting our first little one and we are over the moon! Does anyone know How I can change my due date to accurately reflect what the doctor says? Thanks!
