Switched to Night Shift 7 days late on my period

Elizabeth

So on June 2 I switched to working nights from midnight to noon and I still haven’t gotten my period I had sex 23rd, 24th and 25th either pulling out or using a condom. Trying to chalk it up to stress of starting a new job and the nightshift all at once but still kind of nervous and have no access to a pregnancy test for awhile as I am offshore for work. Any thoughts? Any other symptoms i would have if I was pregnant because I literally feel fine just no period
