Should I take a pregnancy test?

Okay so, for the past few months I’ve been using this app, Glow, and I’ve also been using <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> just to see which one I like better to keep track of periods. Well now I’m late for my period. Glow days by 6 days and <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> says by 10 days. Should I go ahead and take a pregnancy test or do I need to wait?
