Is anyone else using more than one <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">pregnancy app</a> and they say you’re different days? Like for instance, one says I’m 3w 4d the other says I’m 4 weeks. How can they be so different?please tell me someone else is crazy like me and has more than one app. What app is everyone using?whats your favorite and least favorite?
