Day off in Nurture app

BB8

Anyone else a day off in the <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">nurture</a> app? My due date from dr is March 8 and they said I’m 6 weeks 6 days today.

But the app I have set at March 8 th and it says I’m 6 weeks 5 days.

My other app, baby center, has it correct.
