Why are blue veins mire visible in breasts feet and hands over last two weeks. not pregnancy. on period now?

Normal finding: I am amazed about how often I have women ask me about the veins on their breast. Occasionally they are spider veins but mostly they are blue veins. These are almost always normal findings and normal variations of chest veins. They tend to be more pronounced in fair skinned females and they may be related to hereditary factors, levels of hydration and even temperature changes.
