Hoping for a missed period

Here’s a break down of my cycle the past 3 months ;

Sep - 23-27th

Oct - 25th- 29th

Nov - no period and November is “ now “ over but this app and another predicted the 27th or the 29th for a period. I have tried a few times during my fertile window in the month of nov. kinda happy a period didn’t come this month but could this just mean it’s coming later this week? And it could also be too early to test correct? ( sorry I’m sooooo new to all of this. Please educate me ladies 😫💗!!)
