Dry itchy skin, pigment changes, and stretch marks can occur during your pregnancy. An emollient cream may help relieve the dryness and itchiness.
Some women develop brownish discolorations on their face, skin, or a brown line appears in the middle of their abdomen. These are related to hormone changes and will fade after delivery in most cases. Whether you will develop stretch marks on your breasts and abdomen will be determined by your skin type/elasticity, hereditary factors, and total weight gain during pregnancy.
