Big blue veigns on my boobs - pregnant ?

loulou

Hi guys

So I’ve been testing since theee days ( my period Is due Wednesday ) and all came back negative. However I have huge blue veins on my boobs. Could this be a sign of pregnancy? I am taking progestérone suppléments but I did not find this side effect anywhere.

I also have a bit of pain like if my period is coming but different.

Please help!
