I'm 16 weeks and as this being my second pregnancy it's odd that my baby bump is almost nonexistent, yet although in pictures I look small I feel huge. I have gained about 4 pounds and wonder if I'm gaining weight too fast or just if its all in my head. I really feel like I'm at least three times bigger than this and I'm just wondering if anyone feels kinda the same? What makes everyone else feel better when they are feeling like this?
