late ??

Please no judgement just advice.

My period was supposed to begin 2 days ago. I’ve have unprotected sex for about two and a half months now and since then I’ve gotten my periods at the right time. My bf never goes in me he always makes sure that I get mine and he will finish his away from me. I am also not on birth control. I have also been super stressed since quarantine started as I am a students taking 15 hours (now at home) and taking care of two dogs (ones a new puppy) as well as managing my depression through this transition. Anyone know what is going on ? Could I be pregnant or is this stressed related? Also my last period was on the 5 so technically I’m only a day behind? Idk please give me advice/:
