What is the linea nigra?
During pregnancy, the linea nigra shows as a black vertical line on the skin of your stomach. It’s also known as the pregnancy line. It extends from your belly button to your pubic area but can even reach your abdomen. The linea nigra may darken during pregnancy and is particularly evident in those with darker complexions. The term “linea nigra” is Latin for “black line.”
When do you get the linea nigra?
A linea nigra is always present, but it is practically unnoticeable until your hormones rise during pregnancy. The linea nigra darkens enough in most persons to be noticeable in the second trimester (about 20 weeks). Before you become pregnant, the line is referred to as linea alba, or “white line.” Linea nigra occurs when a woman is pregnant and the line becomes dark and apparent.
Does everyone get a linea nigra?
A linea nigra is present in up to 80% of pregnant women, but it may be more or less visible depending on your skin colour. Those with darker complexions have a more prominent linea nigra than those with pale complexions. This is because darker skinned people have more pigmentation than lighter skinned ones.
