Notifications missing

Dara • Director of Innovation, married June 2014, 2 great stepsons and pregnant with a baby boy due 3/28/16!
I have been using both the Glow and <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">Nurture</a> app since getting pregnant because I don't get notifications in <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">Nurture</a>. Yesterday I deleted Glow hoping that notifications would start to default to <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">Nurture</a> but they haven't. How do I fix this?
