A Linea Nigra (language translation is black line) sometimes occurs in pregnancy and is a dark pigmentation of the skin, which takes the form of a black vertical line down the middle of your abdomen. So I thought I'd start a poll to see how many women have had a Linea Nigra in pregnancy, which may occur early or late in pregnancy, but generally around month 4-5 and usually fades around 3 months post partum.
