When should I take a pregnancy test !?

I’m 7 days late and I think I should wait like 2 more weeks so it can be accurate but I’m not sure if that is to long .im active and I don’t use a type of birth control.i just need so guidance through this .my period could just be late but idk if this is tmi but my boyfriend had unprotected sex and he ya know the last time we had sex and we are just worrying to much .
