I am the Cookie Monster

I am hungry ALL THE TIME! This feeling of wanting to eat constantly is very unnerving. According to most online information, I should not be showing or gaining weight in the first trimester. But my belly is protruding, I have gained 3 pounds, and it's probably all from eating too much. I can swear to eating no junk food. All I ever snack on are milk, yogurt, fruits, finger veggies, and granola bars. I don't even drink juice. So, what do I do? I can't stand being hungry, I feel like I will die if I don't eat that instance. But how about that weight? I don't want to end up with C-section in order to remove one giant baby from my womb.
