PLEASE HELP!!!!!

ok so I am on first month lolo birth control and I didn’t start the first pill on my first period day rather a week and a bit later and I don’t know when I’m supposed to get my period. I am a few days late and scared. Is this normal for my period to not be regular yet? Also when I had sex it was 7 days after taking my first birth control pill so I was protected that way and also wore a condom, am I pregnant?! (The condom never broke but I am not completely sure it was 7 days after) ( also my period is not regular)
