Is it common for period to come late after losing virginity?

So my period was supposed to come this week but didn’t, and I’m a little freaked out. I lost my virginity about halfway thru the menstrual cycle, and hooked up a couple times afterwards too. BUT I always used a condom and nothing went wrong. I’m pretty sure I’m not pregnant, but I’m scared bc of the possibility anyways.

I also read online that some ppl had their periods delayed after losing their virginity, and periods could be affected by stress. Could this explain what’s happening to me? I’ve been very stressed over this week due to school and other stuff, and now with this “am I pregnant” thing (I’m a teen with conservative parents :/ )
