Vena azul en el pene. ¿Debería estar preocupado?

Hello everyone, So a week or so ago I noticed a blue vein on the front of my penis. It doesn't hurt or anything when I get erect but I don't recall it being there before. I figure there are so many veins in the penis but I guess this one just is visible. There is no pain or discomfort when I go to the bathroom or do other stuff. Is this serious or should I wait it out? I have to go my doctor for something else in the relatively near future. Perhaps I will mention it when I go. TBH it's probably been there this whole time. I just never noticed or didn't pay it much mind at the time. I do have health anxiety so perhaps this is the new health obsession/worry of mine.
