Type and timing of breast soreness

LittleMissHoop
For you ladies who have gotten pregnant:
Does the type of great soreness differ even pregnant than when it's PMS? 
Also, for the past 3 cycles, my PMS breast soreness has been starting up to two weeks before my period! All my life, breast soreness started 1-2 days before my period. I have regular cycles.  
Thanks for your input!
