Congratulations on your pregnancy! Within weeks your body is going to start changing and you’re going to have to start thinking about maternity clothes to suit your changing shape. The best time to shop for maternity clothes differs for each woman. Some women start to develop a noticeable bump within a few weeks whilst other women may never start to show at all. It has a lot to do with the size of your baby, how you carry your baby and your natural shape to start with.
