How long does a false positive pregnancy test last?

False positives are very common in normal times. There are many reasons for women to have false positives. False positives are very common in life. Many women mistakenly believe that their menstruation is delayed and have symptoms of early pregnancy. They use test strips to test and confirm that they are pregnant. However, when they go to the hospital for examination, they are told that it is a false pregnancy. In this way, many women who are eager to have children are particularly disappointed. How long will such false positives of early pregnancy last?

How long does a false positive pregnancy test last?

A false pregnancy test will make the test paper positive, but it will not be positive for several consecutive days. You can test again after a week or go to the hospital for a check-up. False pregnancy is when there is no pregnancy, but there may be amenorrhea, and a series of symptoms similar to early pregnancy reactions caused by mental stress in women. The HCG test should be negative. If the test is positive for several consecutive days and the menstruation is delayed for more than five days, it generally means that you are pregnant, not a false pregnancy.

Causes of false positive pregnancy test

1. After a woman becomes pregnant, the placenta will secrete human chorionic gonadotropin, which can be detected in the urine.

2. There is almost no HCG in the urine of non-pregnant women. The early pregnancy test strip determines whether you are pregnant by detecting the value of human chorionic gonadotropin (HCG) in urine.

3. Under normal circumstances, there are two results of early pregnancy test: drop urine into the detection hole on the test paper. If a colored band appears in the control area of ​​the test paper (some test papers appear red, some test papers appear blue), it indicates negative, indicating that you are not pregnant. On the contrary, if a clear color band appears in the test area, it indicates a positive result, indicating that the pregnancy is already there.

4. This test has the advantages of being rapid, convenient, sensitive and highly specific. Early pregnancy test strips can only be used as a preliminary screening test. Do not rely on them too much, because false positives or false negatives may occur when using early pregnancy test strips.

5. Some people use early pregnancy test strips and find out that they are pregnant, but when they go to the hospital for a check-up, they find out that they are not pregnant. The early pregnancy test strip shows a false positive.

6. After menopause, under the influence of sex hormones in the body, fat will accumulate in the lower abdomen. Under the influence of the psychological factor of their desire to get pregnant, they believe that they are pregnant, and thus have corresponding "pregnancy" reactions such as anorexia, picky eating and vomiting.

Some physiologists believe that false pregnancy is a combined physiological and psychological "deficit". Some women may not get pregnant for a long time after getting married, but they are psychologically hoping to get pregnant. Once they are anxious, their brains will have strong hopes, and then there is a high possibility of false pregnancy. It is recommended that you check again after a few days after a positive pregnancy test, or go directly to the hospital for a check-up. Only going to the hospital can correctly determine whether you are pregnant.
