Different weeks on glow and glow nurture

Sarah

Does anyone else have different length of pregnancy for glow and glow <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">nurture</a>? Mine is about a week apart (glow <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">nurture</a> says 6 weeks exactly and glow says 6 weeks 6 days)
