I used Glow in August of 2014 and it helped me to get pregnant with my first LO. Naturally, I stopped tracking my period and switched to <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">Nurture</a> until the birth of my son. My period didn't return until January of 2016 which is when I started tracking my period again, but this time in <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>. My husband and I decided to try for #2 in August this year, so I downloaded Glow again and entered all my previous periods.
