I'm 6w1d and since yesterday I've had what I can only describe as a sharp pain in my left breast. I'm quite big breasted and when I lay on my side so the pain ful boob is kinda resting on top I can feel the pain so bad feels lumpy then also all day if I move quick and my boobs move I can feel it I'm so concerned but I can't see my doctor until next week, my other boob is fine just tender and omg my nipples are so sore I'm just concerned about the other pain and don't know if normal as never had it in first pregnancy .. I just don't know how to describe it well or if anyone has been through this? Thank you in advance
