Sex and late ovulation

I had sex (protected) one day before my ovulation was supposedly going to start (according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> and glow). These apps have never been very accurate with my ovulation dates. Its been 5 days and I haven’t seen the symptoms of ovulation arise. I know you cant get pregnant if you are not fertile ( ovulating), but I am extreamly paranoid and just need reassurance. The late ovulation has nothing to do with the sex right? Meaning, i am not pregnant and the late ovulation is mostly due to stress or change in environment?
