hahaha help please

So a while ago I had sex for the first time with my boyfriend. We used protection (condoms) then and the two times we’ve done it after, but my period is late — only by two days, but still. I have the symptoms (acne, sore breasts) and I thought I was in the clear because I bled a little earlier but I haven’t bled since then. I know stress delays periods, and I have an abundance of it, but can someone please tell me how much I should be freaking out and calm my anxious self down? 😅
