The pregnancy test stick has only one line and the menstruation has not come

Women have their first menstruation every month, and usually it comes on time, but now most women have abnormal menstruation, that is, irregular menstruation, such as delayed menstruation. We all know that pregnancy will cause delayed menstruation, but pregnancy tests will show two bars, but some women only have one bar. So why is there only one bar on the pregnancy test stick when the menstruation is delayed?

What is the reason for delayed menstruation and one line on the pregnancy test stick?

If menstruation is delayed and a single line is displayed when using a pregnancy test stick, it means that the woman is not pregnant. Menstruation is often delayed, which may be caused by irregular menstruation. Menstruation delay is a very common symptom of irregular menstruation. Irregular menstruation is caused by internal and external factors. In addition, it is accompanied by abdominal pain and back pain. Naturally, there are many reasons for delayed menstruation. The actual reasons are as follows:

Neuroendocrine disorder is one of them. Generally, it is caused by abnormal function of the hypothalamic-pituitary-uterine-ovarian axis, or it is not stable or has defects, which is what we often call menstrual disease. Of course, it may also be due to the position of the uterus and ovaries, especially for women of childbearing age. If the menstrual irregularities persist, it may be caused by poor corpus luteum function in the uterus and ovaries, which usually leads to shorter menstrual cycles and heavy menstrual flow.

In addition, there are organic or drug reasons, including inflammation of the reproductive organs, growth abnormalities, tumors or malnutrition. Abnormal bleeding during pregnancy is generally considered to be irregular menstruation.

What's the matter with one line on the pregnancy test stick when menstruation is delayed? We all know that once a woman is pregnant, two lines will be shown on the pregnancy test stick. If the test result is one line, it means that she is not pregnant, and the delayed menstruation is caused by other reasons. The actual cause must be found out, and targeted adjustments should be made according to the cause to eliminate the cause and restore the menstrual period.
