Want to know experience..

My period is due on sunday, and the past 3 days my nipples have been really sore, to the point that rolling over in bed hurt them. Then last night when I got out of the shower, tmi my nipples were almost black...just REALLY DARK BROWN!! Have you ladies ever experienced this? I also have been experiencing food and smell aversions, tiredness, bloating and gas.
