Hey girl....don't feel down, you look amazing!!!!! AND I really do think it's allll in your belly, b/c your sides, legs and arms look s-k-i-n-n-y!!!!!!!!
And to make you feel even better, I weighed in at 169 this past Monday and I am almost 2 weeks behind you. Plus, I started out overwight and weighed almost 152 right before getting pregnant. See.....told you I'd make you feel better!!!!!

Damn bc pills made me gain weight after coming off them.....everyone else I knew lost weight after stopping the pill
You'll lose it fast though....you were so small pre-pregnancy!!!!!
Just be thankful you don't have the fat bulging sides that I have now acquired. It's actually very very uncomfortable and looks horrible!!!!!!!
