Breastfeeding

Lisa • Married 5/10/14. Joseph 2/16/15. Cecilia 9/18/16. Due with baby 3 August 18, 2018!!
I used the <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a> to help get pregnant after we were married. Worked the first month. Baby is now 3.5 months old. We practice natural family planning and are currently trying to avoid pregnancy until September when we will try again. I'm currently breastfeeding therefor I have no period. I was wondering if you guys were working on a way to incorporate that into the app. I can't put any a period date because I don't have one. This leaves the app kind of useless to me right now but I love it and would like to continue trying to use it. Thanks!!!!
