It's normal to not show as every woman carries differently. Try and eat small meals if you don't feel hungry for a large meal. If you have had nausea or food aversions then the weight may drop.

Dont worry at all. It is a bit early. And the bump also depends on your body structure too. Its early for a belly.

there is nothing to worry...this is also same with me..after 18 week u start to show ur belly
