Confusing!

These apps are confusing sometimes I’ve got this and <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> which is connected to glow I’ve put in the same information for both and one says my fertility is low today and the other says it’s high don’t know which one to believe I’m one day passed my period 🤷🏼‍♀️
