It's normal your bodybis pumping a lot more blood therefore your veins are noticeably enlarged in size. Mine went back about a week after I delivered my son so I'm hoping the same thing will happen this time around.
Yes it's normal in pregnancy. You will find a lot of your veins become really prominent. It's from the increased blood your body has during pregnancy.
It's normal during pregnancy I've got them to but they're big and green i think it looks gross. It'll go away probably after you stop breastfeeding.
