It is highly possible that your veins will show. Before your period, hormones cause your breasts to swell which can lead to more pronounced veins.
malfunctioning valves in veins
Pulmonary veins. Arteries lead away from the heart.
The blood pressure in the superficial veins is usually low, but if it rises and remains at a higher level over a period of time, the valves in the veins begin to fail and the veins dilate, or expand
Veins will appear blue. Don't confuse this with spider veins. They will often pop out on the hands and feet if you have been doing heavy lifting (hands and feet) or running or jumping a lot (feet). There is likely nothing wrong. If you don't like the blue veins around your breasts then get a tan.
No. Some women just have those. I've always had mine.
Veiny breasts is a sign of pregnancy yes. But some womens breast skin is finer than others and veins are more noticeable. If this is new for you and you have missed a period, yes you could be pregnant.
Yes, but it will be a little darker inside the veins.
You've had swollen and tender breasts for three months with very visible blue and red veins? Why have you not seen a doctor about it?
