Glow vs. eve period prediction

king • Insane baby

I’ve been using <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> to track my period for years. But now I’m trying to get pregnant and Glow has predicted my period to be 4 days from now and it’s supposed to come today. <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> has always been spot on about the predictions of my period. Has anyone else experienced this?
