A little puzzled...

AACaHa13

I am only 4 weeks and a couple days along and I seriously can't stop eating! I have been eating all day for the past week! I am not usually a snacker either. I am thankful that this is my only real symptom.. I'm dreading the fact that m/s could show up soon. I guess I'm just a little confused as to how we can feel so hungry and have waves of nausea this early when your body doesn't know its really pregnant yet? Anybody else have early symptoms!?!
