Does the vertical line on the small abdomen become darker in the early stages of pregnancy?

Patient's question:

No

Doctor's answer:

Actually, this line is what is known as the pregnancy line. It appears during the 2nd to 4th month of pregnancy. Due to the influence of pregnancy hormones, this line can stretch from the perineum to the navel, and in some cases, it may even extend to the chest. Some lines are so light that they are barely visible, while others are dark and may even grow hair. All of these are normal. The growth of hair on the pregnancy line, as well as its quantity and the depth of color, are determined by the pregnant woman's own hormones.
