help! I cant seem to eat much

YC
Ive only just started having aversion to lots of foods about 10days ago (6wk 6days preg today) but im really worried im not getting my baby enough nutrition. I am constantly hungry but nothing smells or tastes enjoyable. When I do find something I like it's usually citrus which upsets my stomach as it becomes more acidic with it having little food in it. Help!
