Am I going to be able to hide it?

Hey, so I'm at 5w5d, and this is my first. Before I fell pregnant, I was 8stone, and I've always been super-skinny. 
I've began to show a little, but it's a lot more obvious when I eat, with me bloating. 
I'm not planning on telling my family or work until I'm at 12weeks/ whenever I get my first scan. 
Is there any way I'm going to be able to hide it for that long? 😕
