Large lump in same place on both breasts

Hey

I noticed I have two lumps developed on both breasts in the same place (outer if that makes sense - quite quickly).  They are about 3cm.  Went for a mammogram and nothing showed up though the very lovely nurse said she could easily feel them & made a note.  Now have a wait of 2 - 3 weeks for ultra sound which is a lot sooner than I was expecting to be honest.  Just reaching out to any other ladies here.  Xx
