Breast tenderness

Lately my breast have been sensitive and they sorta hurt too. I was wondering why? Could it possibly mean I’m pregnant? I’m not sure but my boyfriend and I have been safe we’ve used condoms and checked if there were any tears and such but no we’re clear. My boyfriend and I did have sexual intercourse just yesterday I don’t know if that has to do with it maybe he went a little too rough I’m not sure. The thing is I had already had the sensitivity that day so I had it before. I’ve been experiencing sharp pains as well I’m not sure why. I never really experience this type of symptom , my period is supposed to arrive any time now. Intercourse just throws off my period due date but i don’t know. Can someone help me figure out why this is occurring?
