Glow Nurture

Megan
According to glow <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">nurture</a>, I'm 5 weeks 3 days pregnant, but I'm only 3 weeks 4 days (CD25)... My due date is showing correct (November 20) and my LMP is right If pulling from Glow (February 20), but it's still not right on my weeks. How can I get the correct info without lying to the app about my due date?
