Sore breast

Hey everyone! Just curious if I paranoid! I know I should be asking a gynecologist, but I’m just curious if this happens to anyone else.

So my period is very irregular, except for recently where it’s been coming on the 16 or 17th since January. But my breast have been sore for about three weeks now. I have felt a little nauseous but no vomiting or anything.

But I should also be getting period signs to, but I haven’t really been cramping except like a little! Very little and light cramps.

My question is that is it normal for my breast to hurt for three week before a period?? Cause that really hasn’t happened to me before, they’ve hurt a week or two before, but never three to four weeks!

Anyone else have this problem?
