I really need some advice... 😬

Ok so my boyfriend and I had sex about 4 days before my period was suppose to start and now I'm about 5 days late!? We used a condom and he didn't even cum until after oral sex. I also have been very active (due to training for track) and I know that kinda messes with your cycle... I just don't know what to do? Should I take a test or wait and see if my period shows up?
