Advise please!!

I normally always get sore breasts about 7days before my period and it lasts for 3-4 days. This month I have had REALLY sore breasts and they have felt full/firm since 1/11 with increasing tenderness. My period is due 1/24 and my last period stopped 12/31. I read online that your breasts can become tender at 1-2weeks after conception. I’m wondering if something similar has happened to any of you ladies before getting a BFP? Or any advice on what it could be? This has never happened before so I’m curious!
