Does anyone else feel like they are hiding a secret because they aren’t showing?

I’m 19 weeks and haven’t started showing. Do I look a little fatty in the mid-section? Yes. But not pregnant at all. And when I’m walking around I just want to scream out “I’m pregnant” because I feel like no one can tell. Even when I’m working out, I get so tired and I take a bunch of breaks but to others I just look like I’m slacking off. I just want to be like “I’m not out if shape or lazy, I’m just pregnant and winded!” Ugh, when will this belly reflect my status???
