Dry nipples as an early pregnancy symptom??

Well, the title pretty much says it all. However, I'm only 5 DPO so I really want to doubt that its an early pregnancy symptom as implantation probably won't even occur for a few more days, if at all.

But this is weird. I've NEVER experienced this before. And they're not so dry that they're cracking or painful, but definitely noticeable to the touch. Also, I'd like to point out its not the areola, but JUST the tip of the nipple. I haven't changed soaps or anything in my showering-routine, so I'm kinda stumped.

Any of you ladies experience this in early pregnancy?
