Repulsed by food!

I am 6 wks 5 days today and just this week started with all day nausea. When I am hungry I feel like I'm going to puke but when I think about eating the thought of food makes me want to puke. If I smell food I want to puke. If I see a picture of food I want to puke. Its horrible! Anyone else in the same boat with food aversions? Anything I can do?
