Women with vertical lines on the abdomen, that is, vertical stripes, is not necessarily a sign of pregnancy. Normally everyone has a vertical line on the abdomen, and during pregnancy, some pregnant women will have obvious stretch marks on the abdomen, or the color of the midsection darkens, making the vertical line obvious, but it may also be a sign of obesity, hives, etc., and needs to be judged on a case-by-case basis. In general everyone has a vertical line in the middle of the abdomen, mostly from the navel to the pubic symphysis, often referred to as the midsection. Most women usually have a light white or light brown color due to daily pigmentation, which may go unnoticed. In some women, due to hormonal changes in the body, the midline of the abdomen will gradually become darker and longer, and in some pregnant women, the position of the vertical line may also be shifted. If this is accompanied by nausea, dryness and vomiting, and if you have recently had unprotected intercourse, it is recommended that you use an early pregnancy test, or go to the hospital for blood and urine HCG, ultrasound and other tests to accurately determine if you are pregnant. In addition, vertical lines may also be stretch marks, some women after pregnancy, with the growing fetus, women’s abdomen continues to expand, the abdominal wall beyond the range of skin elastic fibers to bear, so that the abdomen stretch marks. Obesity can also produce vertical lines, due to excessive muscle growth makes the elastic fibers of the skin break, thus appearing vertical or horizontal obesity lines. If a woman is significantly obese, vertical lines may also appear as a normal physiological phenomenon. And some women after allergies or other reasons caused by hives, hives may leave melanin deposits in the abdomen after the hives subside, thus leaving vertical stripes, generally no significant impact on the body, may gradually disappear. Therefore, it is not possible to judge whether you are pregnant or not by the vertical lines on your abdomen. You need to make a comprehensive judgment based on the time of intercourse, menstruation, early pregnancy symptoms, early pregnancy test results, etc. If you suspect that you are pregnant, it is recommended to go to the hospital for relevant tests as soon as possible.
