Times, they are a changin'. You may be noticing some changes in your body, including larger breasts, linea nigra (a vertical brown-black line running down the abdomen), mask of pregnancy (brown patches that can appear on the face and neck), and vascular spiders or angiomas (small red elevations on the skin of the face, neck, chest and arms that extend upward). These conditions may be caused by high levels of estrogen, and most will disappear or recede after birth.
