New to glow and I'm 5 days late according to another period app

So my <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period app</a> I have used for many years says I'm 5 days late I have a normal period, I've taken a test everyday since my "missed period" but glow says my period starts in 2 days I'm so confused. I have sore boobs and no sign of my period what so ever also I've lost my appetite and I have a super sweet tooth every now and then since I've missed my period ... this will be my third month trying after my miscarriage in July. I need advise ? Do I wait it out or keep testing
