Same as other PP, my areoles didn't darken until 2nd or 3rd trimester. At around 6 or 7 weeks they got REALLY sore (like they were bruised all over). I was also a D cup before getting pregnant and went up 2 cup sizes (and only lost one when I stopped breast feeding). Anything is possible!
When I got my BFP with #1, I had no symptoms at all until 2 weeks after BFP.
Good luck!
