Period dates never right

Shelby

I’m on a birth control where I only get my period every 3 months. I changed the length of my cycle in my settings but that doesn’t change anything and <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> is saying I’m super late, my whole calendar is grey, it keeps asking if I started my period, and it no longer tells me any cycle predictions. How can I fix this??
