Hi, I'm new to this app so hopefully someone can help me. After 6months of being spot on, my period was late last month but eventually came three days later. This month I'm late again. I updated saying my period was late. Now it's saying my period should start a few days later. I don't understand how the <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period tracker</a> works.
