Counting in between periods

So when I first lost my virginity about 2-3 months ago my period was delayed by 11 days . I usually get my period 22-24 days In between . A normal period can be in between 28-35 days (according to google) so should I be rlly worried? One of my period apps say I’m late by 4 days today and another says it’s supposed to come today. After I was late by the 11 days my next period the following month came again 23 days later. Today makes it 23 days since my last period and ain’t nothing there ? 🧐
