Sick after eating

KP • Mama of two DD 04/14 and DS 03/16. #3 and last due 3/19
As soon as I hit 14 weeks I thought maybe I was getting the flu. But I'm 15 weeks tomorrow and it's still happening. I wasn't sick all pregnancy until now. But it's only after I eat. I feel nauseated like I ate too much even if I havent. I have to lay down and I'm useless. Anyone else experiencing this?
