White pimples around my nipples

Chelsea
I took a pregnancy test around 3 days ago and there was a faint second line but i have thought so many times i would be pregnant that this time im doubting i am pregnant. Got an appointment on monday to have a pregnancy test at the doctors. This morning i got in the bath and noticed that i have white pimples around my nipples. My breasts have also been so sore the last week or more and the pain dont seem to be going. Can anyone help??
