Irregular period help??

I’m 20 and my period is very irregular, it always has been. My boyfriend and I just recently started having sex (I was a Virgin before him) and I noticed that my last period came later than normal, and my upcoming period should be starting tomorrow, but I don’t have any spotting yet like I usually do the week of. I do have all my other PMS signs though. We ALWAYS use protection and even then he ALSO pulls out. We’re paranoid haha 😂 he’s never penetrated me without a condom. And he pulls out long before he’s going to finish. The condom has never broken or came off. Nevertheless, should I be worried that I’m not seeing my usual spotting?? Or just wait it out a little longer and take a test in a week or so? I’m about to get on birth control pills as well just to give me some peace of mind in the future
