Breast pains

Janice
So I don't know if anyone has any opinions on this. My breasts have been hurting on and off the last few days. I had intercourse about 13 days ago and my period is in  5 days.
 Normally my breasts do get sore for a day during ovulation and the day before my period but never this long. It seems to soon to have any pregnancy symptoms. Does anyone have any ideas?
