For those of you who use <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">Nurture</a> how accurate was the due date vs your Dr. 's due date? The Nurse's estimate that I am 5 weeks based off of my last period, but <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">Nurture</a> estimates me at 2 weeks.. I don't go in for my first apt until May 5th
