Anyone else have soreness at the sides of each breast?  Mine are killing me!!!  I'm having a hard time lifting my arms up....  This just started a few days ago.  I'm 7.3 weeks.  When I look in the mirror they look much fuller on the sides too...  I'm sure it's normal and the growth that is causing this, just curious if anyone else has these symptoms???
