Is it true that my period is delayed for two days?

A healthy woman normally has regular menstruation, which occurs within a few days every month and ends after a few days. However, some people's menstruation is delayed by two days. If this happens during the pregnancy preparation period, you should consider the possibility of pregnancy, but there is no guarantee that it is related to pregnancy, and testing is needed. In addition, a delay of two days in menstruation does not mean pregnancy. It may just be a physiological delay.

What is a pregnancy test strip?

For women who are planning to get pregnant, pregnancy test strips must be familiar to them. This simple pregnancy test method is not only easy to operate, but can also be easily tested at home, and its accuracy rate is also very high. Therefore, many women use pregnancy test strips to detect pregnancy and find out whether they have successfully "upgraded".

How much do you know about the testing principle of pregnancy test strips?

The detection principle of pregnancy test strips is to determine whether you are pregnant by detecting the concentration of HCG in urine. HCG is human chorionic gonadotropin, a glycoprotein produced by the placenta during pregnancy and can be excreted in the urine through the glomeruli. A high concentration of HCG naturally means that a woman is pregnant, but there is almost no HCG in the urine of non-pregnant women.

Precautions for using pregnancy test strips

Many women use pregnancy test strips to do the most preliminary pregnancy check, but if the method of use is incorrect or the purchase is unreasonable, it will affect the normal test results. Therefore, when using pregnancy test strips, you must pay attention to the following precautions when using pregnancy test strips.

1. If the pregnancy test paper you bought is stored for too long (more than 1 year), or the early pregnancy test paper is damp and not kept at normal room temperature (should not be refrigerated), it may become invalid and result in a false negative test result.

2. If the pregnancy has just begun, or there is a possibility of ectopic pregnancy, the HCG level in the body is generally low. The test sample needs to be left to stand for more than 3 minutes (usually only 1 minute), and it is necessary to carefully identify whether there is a weak positive - the color band in the test area only appears faintly.

3. After 3 months of pregnancy, HCG levels decrease and urine tests may sometimes be negative or weakly positive.

4. In extreme 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.

5. A positive result does not mean 100% pregnancy. Because some tumor cells, such as hydatidiform mole, choriocarcinoma, bronchial carcinoma and renal cancer, can also secrete HCG, and there have even been patients with endometrial hyperplasia who tested positive for HCG.
