Tight fitting shirts?

This may sound strange, but I am having a hard time commiting to wearing tight fitting tops. Especially at work. My husband says I definitely look pregnant, but..well, he's a man. I have still been wearing my flowing shirts to cover my "bump" but starting to feel frumpy instead. Does anyone know what I am talking about, or am I being a crazy pregnant lady???? I don't know why I am apprehensive, other than the fact I know people will be looking at my belly... Or that I am not entirely convinced I look pregnant versus that I eat chipotle for every meal.
