Getting bigger or just fatter?

I'm 10 weeks pregnant. And I asked my sister today if I look more pregnant from the last time I saw her. She said "yeah!" I asked her more here (my lower abdomen) or here (muffin top)? And she said my muffin top. So basically I look fatter? I've been eating pretty good. I don't know why I am getting fatter and not more pregnant. I can't tell! Did any of you ladies have this problem?
