Areolas are Loosing Color

Amie

I’m 11 weeks and 5 days. I noticed last week that my areolas are loosing color. The nipples and areolas used to be the same very light brown color now the areolas are the almost the same color as my flesh and my nipples are light pink. I thought nipples were supposed to get darker. Are my hormones out of wack? It’s Christmas so I can’t call my OB until tomorrow. Anyone have this happen or know what might be going on?
