Veins on chest and breasts good sign?

Christina
As I was getting ready for bed I noticed blue veins on my breast, chest and shoulder area. My breasts have been very soar since 4 dpo. I'm right now 7dpo. Was wondering if this is a possible sign of pregnancy? We've been trying for 7 months now. I started googling this and got mixed feeling and don't want to get my hopes up.
