(TMI) What could this be?

Any of you ladies had these little bumps? they appeared around my nipples. I don’t know what they are I’ve tried looking online, it says it’s normal. But my boobs have been killing me for a week now. Super sore, heavy & sensitive nipples. I’ve been crampy and tired. Could it be pms symptoms? I’m 10dpo and testing - AF is supposed to come soon.
