Is this normal?

I apologise in advance as I am posting a picture, 
I was waiting for tomorrow to see if af showed but I started getting some bleeding today, nothing heavy or anything like my usual period. 
The reason I'm concerned is my breasts have had a lot of blue veins almost like a road map + there's darker blue veins on the areolas and I've read online that it's a sign of pregnancy? But with the bleeding today I thought it was af! Has anyone else had this and not been pregnant? Maybe a pms symptom or something like that? Please help 
(The veins are bluer in the picture and they show a lot more the lighting wasn't great so my camera isn't picking it up very well) the bleeding today only lasted about 8 hours it stopped now :/
Thanks
