A vertical line on a woman’s stomach is not a symbol of pregnancy, basically all women whether they have had children or not will have a vertical line, including men will also have this vertical line, this is the abdominal white line, is a normal physiological phenomenon, no other corresponding symptoms appear, so do not give intervention. If a woman is pregnant, especially after a large month of induced labor or hospital delivery, some people may leave stretch marks on the abdomen, which are often silvery-white and may have been pregnant in the past, but it is not absolute, because some people are relatively fat, through weight loss or through exercise after weight loss, the abdominal wall is relatively loose may also appear similar to the phenomenon of stretch marks, but not the real stretch marks. It’s not a real stretch mark, it’s a matter of medical history and analysis, and having stretch marks doesn’t necessarily mean you’ve been pregnant.
