Why are there two bars when you are not pregnant?

The pregnancy test stick is a well-known early pregnancy test tool for many women. Many people know that when the pregnancy test stick shows "one bar" it means you are not pregnant, and "two bars" means you are pregnant. But are pregnancy tests 100% accurate? For example, why are there two bars if you are not pregnant? Let’s take a look at the interpretation below.

What if there are two lines on the pregnancy test stick but no pregnancy?

The results of pregnancy test sticks are for reference only. There are many factors that may affect the results of pregnancy test. Therefore, if you want to be more certain, it is best to go to the hospital for examination. The results of self-testing with pregnancy test sticks should only be used as a reference. There are many factors that affect the detection results of pregnancy test sticks. For example, within 7 days after a woman ovulates and has sex, when the HCG hormone in her body is still relatively low, it is easy to detect a false negative using a pregnancy test stick. In addition, if the menstruation is delayed for more than 7 days and the pregnancy test stick tests negative, don't be lucky at this time. Something must have gone wrong at some stage when your "best friend" is forbidden to visit. If you go to the hospital for a blood test at this time, the result may be positive.

This kind of situation is often due to the quality problems of the pregnancy test stick itself or improper methods of the operator. Such factors as whether the pregnancy test stick is expired, whether it is damp, whether it is of unqualified quality, whether the operator inserts the correct end into the middle urine, whether the test urine is non-morning urine of early pregnant women with low female hormone secretion, whether the test result is checked between 3 and 5 minutes, etc., all of these factors will affect the test results. Therefore, the results of pregnancy test sticks during pregnancy are not 100% accurate. If you want to know whether you are pregnant or not, it is recommended to go to a local hospital for blood tests, B-ultrasound and other auxiliary examinations to confirm it. Liu Yan reminded that when looking at the pregnancy test stick, you must clearly identify the comparison line and the detection line. If the comparison line does not appear, it means that the test is invalid or unsuccessful.

It should be noted that when the pregnancy test stick shows "two bars", do not think that you are pregnant and do not do further testing. Because "two bars" does not necessarily mean pregnancy. In addition to the human chorionic gonadotropin in the urine which can cause two bars to appear on the pregnancy test stick, some tumor cells or hydatidiform mole in the female body may also cause "two bars" to appear on the pregnancy test stick.
