Help me!!

So my ex and I had sex on Tuesday morning like 5 times unprotected one of the times I’m pretty he came in me but I could be wrong when I got home this had been hours after we had sex but I got in the shower and noticed a lot less white discharge it was there but it smelt like bleach and normally it smells like my natural smell idk how to put it 😂 but could that be sperm? I’m supposed to get my period on Tuesday if I don’t get it should I take a test?
