Light pink mixed w/discharge

So about an hour ago I went to the bathroom  and when I wiped I noticed a little pink. 😳
I seriously had to double check just to make sure. Then I checked my panties and there was a little pink mixed with Discharge there as well. 😢
I'm not having any cramping, just mild cramping here and there. I'm just worried.. Is this bad? I am gonna call my ob when I get home from work but I'm just kinda worried and stressed now. 
I had an ultrasound yesterday and everything was fine. Last night I was soooo nauseous I could barely fall asleep. And I threw up 3 times yesterday. 😓😓😓
And I've been nauseous all morning 😷😫😫 is this normal? Or is it a sign of miscarriage??😖
Btw I'm 7 weeks 2 days
