Need your opinion asap please

Ashlee
Af is due Jan 6. I'm feeling really weird though. I have this weird feeling in my stomach that is hard to explain. It's almost like this strange pressure. I'm gassy, way way way more than usual when I'm about to start. Have to go to the bathroom a lot (#2 constantly). I get sick to sights that never made me sick before (I love scary movies. Whenever i see blood or anything gross I puke). Also I have some discoloration in my vagina. The inner lips are a darker color and my breasts are sensitive. Any opinions?
