What is the chance of not being pregnant if the pregnancy test stick shows one light and one dark

I believe everyone is familiar with pregnancy test sticks. Nowadays, many women who are preparing for pregnancy usually use pregnancy test sticks to conduct pregnancy tests one week after having sex during ovulation in order to announce the good news of their pregnancy to their families as soon as possible. I believe many people are also familiar with the test results of pregnancy test sticks. One line means no malformation, and two lines mean pregnancy. But what if the pregnancy test stick has one dark line and one shallow line? Do you know the probability of not being pregnant if the pregnancy test stick has one dark line and one shallow line? I'm going to explain it to you guys below.

Instructions for use of pregnancy test stick

1. Higher accuracy: This product has high accuracy because it uses a double-layer super-sealed aluminum foil packaging to ensure that the product will not be easily damp for a long time. Even if the product is stored for 2 to 3 years, it still has a good quality level.

2. Detect early pregnancy earlier: This product has high sensitivity, that is, it can be detected two days after the sperm and egg combine and the embryo implants in the uterus, which means it can be detected about 7 days before the next menstruation.

5. More convenient to use: This product's unique patented direct urine collection design eliminates the inconvenience of using a urine cup to collect urine and a straw to suck urine. It is convenient to directly collect urine on the urine suction hole of the pregnancy test stick and load the result from the window. When collecting urine, wear the included disposable plastic film gloves to prevent your fingers from being accidentally splashed with urine. The whole process can be easily carried out in the bathroom. The pregnancy test stick can be discarded immediately after testing, which not only protects privacy but also is clean and hygienic, and is very convenient.

Pregnancy test stick one dark and one light result explanation

Pregnancy test sticks are generally more accurate. The accuracy of morning urine testing is higher. If the test shows one dark and one light color, it may be positive. It is also possible that you are pregnant, but the pregnancy period is relatively short. In this case, you can wait for about a week before testing again. At this time, the two colors will be the same dark. Or you can go to the hospital for a blood test to confirm and you can also do a progesterone test at the same time.

Although the use of pregnancy test sticks is simple and convenient, there are many details that need to be paid attention to during the use process. Because when people use pregnancy test sticks, most of the time it is when the sperm and egg have just implanted. At this time, the HCG value in the body is not obvious. We must use morning urine for the test to be more accurate, and we cannot drink a lot of water before the test, otherwise it will dilute the HCG component in the urine and affect the test results.
