Could this be a good sign!!?

Could this be a sign? With my first pregnancy I never felt my boobs grow or had any indication that my boobs were sore. It wasnt until the very end of my pregnancy and that I finally felt the odd sensation in my nipples and had sore boobs due to my milk supply. I havent felt anything with my boobs since, my daughter is now 2.5. Last night for the first time in years my nipples hurt... it went away after a while, but I woke up with some more soreness. I am only 6dpo. What do you think ladies? Would this mean I could test earlier than a missed aunt flow?
