I used glow for 4 months and every month as I tracked my period it would update my most fertile days. Well on month #4 glow was spot on. I took a test 2 days after my period should have started and got my BFP. This is baby #2. For my first I tried for 10 months before getting pregnant. I love being able to communicate with other women and being able to track my Heath. I am now using glow <a href="https://play.google.com/store/apps/details?id=com.glow.android.nurture">nurture</a> for my pregnancy. Currently 5weeks and 3 days and hoping for a safe and healthy baby/ pregnancy.
