No appetite, constant nausea

Chelsea
The only thing that sounds remotely good to me is ramen noodles, which have no nutritional value whatsoever. I'm thinking about buying some Ensure to sip on through the day to get more nutrients but I'm honestly afraid to gain too much weight during pregnancy (I heard ensure makes you gain a lot of weight) I know, it's dumb. I'm miserable because I feel hungry but nothing is appealing! Does anyone recommend Ensure? Or another way to get nutrients?
