loss of appetite ..

9w5d and for the past 3 days I've had no appetite .. I have to force myself to eat.. I'm just not hungry ,or rather nothing sounds good or appealing so I just don't eat.. I know that's not good I'm just wondering if there's any remedy to this that may have worked for some of you . I force myself to have a little fruit at least ,but when I do eat I get sick.. I'm drinking water and taking my vitamins but as for food I can't get it down. I should add that I have horrible heartburn.
