Yeah same thing with me. I'm 8 weeks today and can't eat breakfast without throwing it up. I pretty much lost my appetite and only eat certain foods now since everything I use to love seem so gross now.
Thats how I was in the first trimester. Try drinking water and having a fruit. Dont worry about it, just eat as soon as you get hungry. In my second trimester is when I couldn't stop eating; I gained weight like crazy.
I didnt get an appitite until recently around 14/15 weeks, (im 16 weeks today) all the weeks before I would take a bite or two of something and quit eating.
