Same here. I'm currently a 38DDD. My left boob has a really large vein that's buldging. Thought I was the only one.
The veins in mine having been like that for a few months now and I am a 40HH, And I am getting big.
Is normal and due to an increase in your blood volume to accommodate your little one. Should go away after you give birth :)
Mine are too girl! I'm a 34C and my boobs look black from all the veins haha I'm 28 weeks
thanks girls..just glad to know not just me..
