Why are my boobs STILL sore?

So this is very different than what I'm used to and I don't want to freak out. The last of my period was 4 days ago, I had a regular period like I always do. Yes, I've been on the pill for almost two years now. My concern is why do my boobs feel so heavy and sore af? This has never happened before. Usually my bf is fine with feeling on me but for these past two days I told him don't even think about touching my boobs.
