hunger

I eat so much in a run of a day its crazy but yet my stomach growls like i havent eaten in 2 days & it annoys me the fact that my stomach never ever stops growling.. is it just me or is this normal in pregnancy? Having my stomach growl after i eat a big meal makes me nauseated to the point i throw up and have to end uo eating again and then my stomach still growls. should i go see a doctor about this? can this be bad?
