Sore breasts come and go?

I always have quite sore breasts 1-2 weeks before AF then when AF arrives the pain goes

however I have had severely sore breasts the last 2 weeks but the pain has seemed to ease, it will come back bad again then ease again. I’ve never had this before, has anyone ever experienced this?

I am hoping this is my month as I think I may have have implantation bleeding last week and my emotions have been all over the place and again had severely sore breasts.

I have unusual periods but the last 2 months it has arrived on the 11th so I am going to test this weekend

Thanks in advance x
