Pregnancy two bars picture

You can use early pregnancy test strips or pregnancy test sticks to self-check whether you are pregnant. If two red bars appear during the test, it indicates a positive reaction during pregnancy. But sometimes the test results can be false positive. So, besides pregnancy, in what situations would two bars appear?

1. Quality issues of early pregnancy test strips. If the early pregnancy test paper used is an expired product, the drug ingredients contained in the early pregnancy test paper may change after the shelf life, so the test results may not be accurate. Sometimes, even if a positive reaction with two bars appears, the woman may not be pregnant yet.

2. Problems with the inspector’s actual operations. When using early pregnancy test strips or pregnancy test sticks to test whether you are pregnant, you need to follow the instructions. For example, the mid-morning urine needs to be used, and the observation needs to be carried out within the required time. If the collected urine sample is not up to standard, the observation time has not arrived, the request times out, etc., it will also affect the test results, and the displayed results may be out of frame.

3. Causes of drug effects. If a woman has taken medicine recently, there will be drug components in her urine. Collecting this kind of urine for testing will result in a false positive reaction. Therefore, even if there are two bars, one dark and one light, or two red bars, it may just be a positive reaction of the drug effect, which will also affect the accuracy of the early pregnancy test paper or pregnancy test stick.

How long does it take to detect early pregnancy?

1. Generally speaking, women can usually test whether they are pregnant about one week to 10 days after they actually become pregnant.

2. Once the male sperm and the female egg cell combine to form sperm and egg, about 7-10 days after the embryo implants in the uterine wall, the pregnant woman's embryo will secrete a special substance called human hCG gonadotropin, which is often referred to as hCG in medicine. It only exists in the pregnant woman's body. About a week after pregnancy, human hCG gonadotropin will appear in the pregnant woman's urine, but in the first few days of pregnancy, the excretion of this substance is relatively small and it is not easy to be detected. It is usually more obvious 10-14 days after pregnancy.

3. Generally speaking, about 18 days after normal sexual life, you can determine whether you are pregnant by testing urine, especially morning urine. After sexual intercourse, you can test whether you are pregnant in the first week, or at the latest about 3 weeks.
