Varicose Veins?

I know its mostly common to get them on your legs and thighs, but this morning when I was in the shower I noticed a blue vein on my back. Sure enough when I sat backwards on the counter, there were more. They're very tiny, but very blue. I don't have many but are these varicose? I tried looking it up, but they had no information about getting them on your back.

Also they aren't even an inch long yet, and they're spread out, some areas they're there and then in some they're not. 

Do they look "engorged?" Or knotted?

I have them on my pubic bone and girl regions  

Not yet, right now they look like spider veins. I have some on my thigh too. Which are worse than the ones on my back.  

i only have them on my breast , that was my first sign of me being pregnant.
