Question regarding sore boobs

kt012885

This is my second pregnancy and 1st child.  Nausea kicked in bad about a week ago- and I didn't have that at all my 1st pregnancy.  However I remember my boobs being soooo sore last time pretty early on.  This time around- they are a lil sore-but not bad at all...I mean someone would have to punch me in the boob for it too hurt.  Has that happened to anyone else?  I didn't know since I had been pregnant before- that maybe that's why they aren't so sore yet?  Just curious!  Thanks!
