L.M.
My friend and I both were pregnant at the same time - she did the cutest thing which was on Halloween she dressed up as a chef with a chef hat and apron and a t-shirt that said bun with an arrow pointing to her belly. I was jealous of her cute idea! Halloween may be too far along for you - you'd be 20 or so weeks by then but you could dress up and take a pic and then save the costume for halloween. :-)
