My period is not supposed to start for a few days but the app won’t let me delete my current period. What is going on?

Glow

To maintain the accuracy of our algorithms, you cannot delete your very next expected period. However, if your period is a few days late, you can simply push it out in the app, day by day, until Glow and your period are back in sync. We realize that this is less than ideal, and we are looking into better approaches to this problem.
