UPDATE in early pregnancy - no sore boobs?!

There is a big possibility that I'm pregnant (7 days late with nausea, and a little food aversion), I obviously haven't tested yet because I want to be 2 weeks late before I test. Anyways, my boobs aren't sore, but my nipples are a little swollen, and slightly darker then they were a couple weeks ago. 
Is that normal to not have sore boobs? Is every womans symptoms different? Kinda new to this. 
Thanks for the input. 
UPDATE negative blood test. Guess I'm just late because. Thank y'all.
