My boobs have been hurting for three or 4 weeks now

Hey I was just wondering if this happens to anyone else? My breast have been sore for about three or four weeks now, I should be getting my period today or maybe Saturday! But it’s very unusual for them to hurt for that long of a period, has that happened to anyone else before a period? I’ve read online that it usually will start anyone where from two to one weeks before period but I’m sure I’m just paranoid!
