I downloaded the <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a> after three months of trying unsuccessfully to conceive our second child. I learned a ton of great things from the app and the forums, too. Particularly the SMEP approach. (If you haven't heard of it, check it out!) After only one month on glow, we were so surprised to see that positive test- amazing!
