Only one sore breast week after ovulation but week and a half before period. Never experienced before. Help?

I ovulated almost a week ago and we had sex twice during my fertile days. My period is a week from Monday. Usually my boobs, more specifically my right boob, is sore either the week of my most fertile time or the week before my period so for how it usually goes it's too late for the soreness to be from ovulation but too early to be from my period. Has anyone else experienced this? I assume it's still one or the other it's just that it has never happened at this time before so it's just kinda weird and not normal for my body.
