Tenderness? Five days before expected period day

Lisa
I am hoping to be pregnant I tested a little early a few days ago and my period should come approx Friday, well according to this but I was a little late last cycle( had a early miscarriage in May. So Idk if cycle is still being funny. But as of this morning my breasts, especially the right, are kindof tender. Are there any differences in soreness  when it pms soreness vs pregnancy soreness?
