Heavier than it looks

Huanita
Hi there! I'm 5,7ft (1,74m) and weighted 156lb before getting pregnant. Now I'm on my 26w4d, and weighting 182lb. This week i have an appointment with my doc, and I know she is goint to speak to me because since out last appointment i gained 8lb... But the thing is that i don't look that heavier than before... I'm only with gigantic boobs and belly. My face is thin, as my arms, legs and everything. Everybody says that i don't look like I'm pregnant. Anybody out there like me? Sometimes I even doubt that there is only one baby boy inside me LOL!
