You may find that you have gum issues from an increased blood flow and a lack of Vitamin C. Oestrogen and Progesterone are stimulating milk-producing glands in your breasts, which is why you may need to increase your cup size. You also may start ‘showing' a tummy around about now, but it differs from woman to woman. You may also notice a milky discharge (leucorrhea), which may continue throughout your pregnancy.
