If your blue veins are showing in your wrists is that a sign your period is coming or is that a sign of pregnancy?
First, ALL blood vessels just under the skin look blue. Blood vessel color, or whether flatter or puffier, is NOT a pregnancy symptom. You might be confusing facts with a later pregnancy sign, when blood vessels in the breasts engorge (e.g. the vessels look bigger).
Blood vessel color, size, or appearance anywhere that vessels are seen through the skin also has nothing to do with menstruation.
