Expectant mothers who are preparing for pregnancy will bring many small tools, such as ovulation test strips, pregnancy test sticks, etc. Many female friends who are preparing for pregnancy are mentally nervous and often experience a delay of one or two days in menstruation. They will habitually conduct self testing to avoid pregnancy without realizing it. The pregnancy test stick is an important and common tool for pregnancy testing. Let's learn about what happens when the pregnancy test stick does not display.
What's wrong with the pregnancy test stick not showing
Although a pregnancy test can determine whether a woman is pregnant, here are a few tips for female friends who need a pregnancy test to improve the accuracy of using a pregnancy test. Firstly, try to use the first morning urine test as it is the easiest time to detect hormone levels. Don't drink too much water just to increase urine, as it dilutes hormone levels. If no control line appears within 5 minutes, it indicates that the experiment is invalid or failed.
Do all pregnancy test sticks have watermark lines
The vast majority of pregnancy testing products on the market use colloidal gold method to qualitatively or semi quantitatively detect HCG in urine based on the double antibody sandwich principle, in order to determine pregnancy. It is worth noting that such pregnancy testing products are not 100% accurate, and certain diseases may also lead to an increase in HCG concentration in the body, resulting in false positive results.
The watermark refers to the second line, and the first line is just a reference line. The pregnancy test stick is one deep and one shallow. If you can vaguely see a little red at the position of the second antenna, then it is considered a watermark.
A pregnancy test stick usually yields results within five minutes. If left for half an hour, it becomes inaccurate and meaningless. Moreover, a pregnancy test stick cannot detect pregnancy after twelve days of sexual intercourse. Generally, a pregnancy test stick needs to be used to detect pregnancy five days after the menstrual period is delayed.
The correct usage of the pregnancy test stick is a prerequisite for everyone to use it. At the same time, it is recommended to have a correct understanding of the measurement of the pregnancy test stick. Of course, it is generally recommended to have the test done in the morning, as this will improve accuracy. Sometimes, if the pregnancy test stick does not show pregnancy, it is likely that there is no pregnancy. Don't be discouraged, relax and it is easier to conceive.
