Morning sickness

Okay so I throw up every time after I eat I’m 7 weeks 4days. I get so sick even after drinking water I throw up. I always like cough before I vomit does anyone do that. After I throw up I get so hungry cuz it’s like my tummy is empty but I can’t keep food down. Pregnancy is not what I expected but I’m grateful because I’ve had two losses before this and I’ve never experienced symptoms. Can anyone relate???
