PINK NIPPLES - EARLY PREG??

Allie
Ok, I've never noticed this before and neither has DH. But, I am 9dpo and 4 days till af. I have had very sore boobs for about a week now and now, the areola is darker but the tips are really pink now... Had some pinching pains lower right today a d been dizzy, nauseous on and off for also about a week. Any idea if the pink nipples is a symptom?
