should i be less anxious?

hi! basically condom broke on 23th February and we realized after minutes. he pulled out but came on my back. took plan b anyway after an hour. previous period was on 6th of february. but i got my period on 2nd march (3-4 days early) now and it was like my other periods. (heavy flow first 2-3 days and now as of march 6 its low) im gonna take test on 14-16th to see if im pregnant or not. but im so scared im kind of experiencing bloating and got a cold so my body is kind of a mess 😭 how do i calm down
