Always have sex on peak day but never ovulation ?

I'm just wondering if anyone had this be their issue or could this be an issue? I've been trying for almost a year. We always BD the peak day and usually many days before peak. Usually there's always a reason we don't on actual ovulation day (a lot of it is being over it after doing it so many days leading up) And out of all these months trying we probably only did once or twice on that actual day.

Could this be a reason I'm not getting pregnant ?

This month I'm not gonna try to have sex unless it's the peak and ovulation day so that we don't get "over it" after doing it for so many days leading up to it.
