Spotting instead of period

I’m currently two days late on my period. My boyfriend and I a couple weeks ago had some outercourse (humping with no clothes and a condom) and we both came. There were no rips in the condom, or anything that looked off. I am paranoid now though because my period is two days late, and I think it is most likely from either stress or over exercise but I am still worried. I tried to induce it by masturbating because that worked for me once but this time I just got some spotting and cramps for an hour or so and then that stopped too. I know two days is not much but I am still worried because I’m only 21 and don’t want kids for another 5-10 years. Could it just be late from stress/over exercise? Should I take a test or wait?
