maybe a weird question but I dont find I eat much more then before i was pregnant

I'm 4 months.pregnant and I dont find I eat to.much more then i did.. now I eat a fruit smoothie everyday cause I never ate much fruit and need it and drink milk for the same reason but the only thing that basically changed was.i get something to.eat for breakfast on the way to work.. I dont normally snack or eat after supper. now in saying that if I feel hungry I eat but I don't feel hungry much more then my 3 meals a day..is this normal should i be having all kinds of weird cravings or eating alot more? I havent had any symptoms beside sore breast and getting bigger..this is my first child and everyone is telling me they couldn't stop eating wanting weird foods etc but I'm not like that.
