Will the bar on the pregnancy test stick disappear?

If you find that your period has not come on time, and you are in good health and have no discomfort, you can try using a pregnancy test stick to check whether you are pregnant. Although pregnancy test sticks have a relatively high accuracy rate in detecting pregnancy, expired pregnancy test sticks cannot give accurate results. Similarly, if the pregnancy test stick is contaminated with other substances, it will also cause deviations in the test results.

1. It may be due to biochemical pregnancy.

That is, when the sperm and egg meet and combine, HCG will be secreted 7 days later. When the tiny embryo successfully implants, we can measure HCG, but if the embryo fails to develop, it will no longer secrete HCG.

If there are two lines on the pregnancy test stick, one dark and one light, and you cannot detect it later, it means that the fertilized egg did not successfully reach the uterus, which means that you are not pregnant.

It may also be that the secretion of HCG is too little and the test is not ready.

Generally, the pregnancy test sticks used at home use HCG to detect whether you are pregnant. When you first become pregnant, the amount of HCG is not much, and it will take at least a week for it to increase. If you use the pregnancy test stick too early, two bars will appear.

2. Ectopic pregnancy can also cause your HCG to be low

To put it simply, ectopic pregnancy means that the fertilized egg does not enter the uterus, but instead settles down somewhere else. If you do not go to the hospital early, it will cause abdominal pain and heavy bleeding.

After you become pregnant, your HCG will increase rapidly. If your β-HCG is greater than 66% every two days, it can basically be determined as an intrauterine pregnancy, but if it is less than 66%, it may be an ectopic pregnancy.

If you find that your period is not only delayed, but also has the above symptoms, you should go to the hospital for a check-up immediately.

3. When using a pregnancy test stick, you should pay attention to the following points:

1. It is best to use the first urine when you wake up in the morning, because your hormone level can be easily checked at this time in the morning. If you accidentally forget, you can only hold your urine for four hours before going for the test.

2. Don’t think about increasing your urine by drinking water, as this will affect your hormone levels.

3. Before using the pregnancy test stick, please read the precautions carefully and perform the pregnancy test according to the steps above.

4. Taking some medications may also affect the test results, so please read the label instructions carefully.

5. You should note that ectopic pregnancy is also a type of pregnancy. It will not tell you that it is an ectopic pregnancy, so if you find that you are pregnant, you should go to the hospital for detailed tests.

6. Do not use the pregnancy test stick again after using it once. If there is no result, it may be because you did not follow the steps or the pregnancy test stick has expired.
