Appetite in the first trimester

Am
Well, I just found out in pregnant. I'm 6 weeks now I think. And it's like my eating habits have gone down hill since finding out. I barely eat, like I feel I should. My appetite has completely changed. Certain textures I just can't do. Which is totally out of the ordinary. Any advice on what I can do to eat more? I'm working out, and it's not helping.
