A streak in the stomach during pregnancy does not mean anything to be worried about because it is normal and every woman experiences it during pregnancy. This line on stomach during pregnancy gradually fades after the birth of the child. This line is black in color and vertical, which extends from the belly button (navel) as a landmark down to the pubic bone area. It is formed due to the increase of hormones. Pregnancy hormones are responsible for these pigmentation changes.

When it is light in color, it is called “Linea Alba” but it later turns into a dark line on stomach during pregnancy.

Well, there is no exact reason for its formation, but it is believed that it appears due to the increased levels of hormones in your body .
Medical experts believe that a hormone produced by the placenta, which is melanin, causes the black line in stomach during pregnancy. It is believed that melanin gives color to your body and its quantity increases during pregnancy, causing deep lines. However, there is no explanation as to why it only affects certain areas, such as the stomach.

Is the pregnancy line visible in everyone?
Yes, almost every woman develops an early pregnancy line on stomach/ a line below the navel during pregnancy, although some women may be exceptions. The intensity of deep lines depends on your skin color; Dark lines (Linea nigra) are more pronounced in women with dark skin than in women with fair skin. This is because dark skinned women have more pigmentation than fair skinned women. If a woman has linea nigra (early pregnancy line on stomach) in her first pregnancy, there is a possibility that this line will form in the next pregnancy also.
Why does Navel come out during pregnancy?
The protrusion of the navel along with Linea nigra during pregnancy is seen during the second trimester or around 20 weeks. When your baby grows in your uterus, it puts pressure on your abdominal walls, causing the navel to protrude. This is very normal and harmless to your body. Ingress of the navel during pregnancy is seen in very few women. A few months after delivery, your navel comes back into place. If your navel sticks out during pregnancy, there is no need to panic, because it is normal.
When does the linea nigra go away?
The linea nigra, often called the pregnancy line or black line, usually begins to fade after you give birth, as your hormone levels gradually return to normal. For most pregnant women, this dark vertical line on the belly becomes lighter over the course of several weeks to a few months postpartum. In some cases, especially for women with darker complexions or higher melanin production, the linea nigra may take longer to disappear—sometimes up to a year or more. While the line often fades completely, it may remain faintly visible for some women, depending on their skin tone and individual hormone levels.
Factors like sun exposure can also affect how quickly the linea nigra fades. Protecting your skin by wearing protective clothing and limiting time in direct sunlight can help minimize the appearance of the pregnancy line. Eating a healthy diet rich in folic acid—found in green leafy vegetables, citrus fruits, and whole wheat bread—can support overall skin health during and after pregnancy.
It’s important to remember that the linea nigra is a completely harmless and natural part of pregnancy. It does not have any adverse effect on pregnancy outcomes or your baby’s health. According to the American College of Obstetricians and Gynecologists, this skin change is totally normal and does not require any medical treatment or specific tests. If you have concerns about the line or other skin changes, your healthcare provider can offer reassurance and advice.
Finally, don’t be swayed by the old wives’ tale that the length or position of the linea nigra can predict your baby’s sex—there’s no scientific evidence to support this. The presence and duration of the linea nigra are simply a reflection of the hormonal changes your body goes through during pregnancy. With time, patience, and good skin care, the line will usually fade, allowing you to focus on enjoying your new baby and embracing the natural changes that come with pregnancy.
Bottom line
You should not worry about temporary changes like the line on stomach during pregnancy. When a line is formed on the stomach during pregnancy or the navel going in during pregnancy, etc., because these are not harmful. Take care of your body during pregnancy. Make sure that you regularly massages and moisturize your belly to reduce these Linea Nigra, pigmentation and stretch marks on your belly.
