What they are: The small red or bluish veins that appear mostly on the legs, though sometimes on the face or elsewhere, might appear in a sunburst or spiderweb pattern or as a series of short, unconnected lines. Spider veins can occur alone or with varicose veins. 

What causes spider veins during pregnancy: Not only are your hormones raging at their highest level in your life, but the increased volume of blood you're carrying creates significant pressure on your blood vessels, causing even small veins to swell.
