Wrong dates and notifications! Frustrating!

Glow says I’m 5 weeks and 3 days

<a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">Nurture</a> says I’m 3 weeks and 5 days

I just got a notification I’m <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">nurture</a> that I’m 5 weeks!

Which one is it?

I’m about to delete this app!
