Will there be a weak positive before menstruation?

Pregnancy test sticks are very convenient now. When women want to know whether they are pregnant or not, they will choose pregnancy test sticks to check. Generally, the efficiency of the test is relatively high. If the pregnancy test stick is checked before menstruation, there may be two situations, either negative or positive. If a weak positive result is found, there are mainly many reasons. It may be pregnancy, or it may be an error in the test, such as the test paper being stored for too long, etc. Of course, you must be alert to ectopic pregnancy, hydatidiform mole and other reasons.

Will the pregnancy test stick show a weak positive result before menstruation? In general, there are two results of early pregnancy test paper: 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 show red, some test papers show blue), it indicates negative, indicating that you are not pregnant; on the contrary, if a clear colored band appears in the detection area, it indicates positive, indicating that you are pregnant. However, early pregnancy test strips can only be used as a preliminary screening test and you should never rely on them too much. 1. If the test paper you purchased is stored for too long (more than 1 year), improperly stored, refrigerated, or exposed to moisture, it may become ineffective and result in a false negative test result. 2. If the pregnancy has just begun, or there is an ectopic pregnancy, the HCG level in the body is generally low. The urine to be tested needs to be left to stand for more than 3 minutes (usually only 1 minute is needed), and careful identification is required to determine whether there is a weak positive result - the color band in the test area only appears faintly. 3. In extraordinary cases, such as hydatidiform mole and choriocarcinoma, the HCG level in the body will be too high and the urine test will not show a positive result. 4. After 3 months of pregnancy, HCG levels decrease and urine tests may sometimes show negative or weak positive results.
