For two weeks now I've had sore boobs, first week it was just my nipple that was sore but day by day it's gone into all of my boob (both of them) and they are so sore to even touch. Anyone know what could be causing it? I did a pregnancy test yesterday and it was a bfn. No idea when af is due as I had implant out 2nd July. But I never normally have any af symptoms or pain anyway. It's annoying me now as I have no idea what it is
