Two lines picture of pregnancy test stick

When the sperm and egg combine and begin to develop, two bars, one dark and one light, will actually appear. When the sperm and egg combine for complete fertilization, two bright red lines will appear, which means that you are pregnant. If you want to check whether you are really pregnant, it is actually recommended that you go to the hospital for a check-up, because sometimes the pregnancy test stick is not completely accurate and there may be margin errors, which is also related to the time of our test. So what does it mean when the pregnancy test stick has two lines, one deep and one shallow?

The pregnancy test stick uses the reaction displayed by the fusion of single or multiple HCG antigens in the device with antigens in urine to determine whether the pregnancy is present. Many women choose to use pregnancy test sticks to detect whether they are pregnant. The pregnancy test sticks mainly determine whether the woman is pregnant based on the comparison line on the stick. Generally speaking, there are several types of coloring in pregnancy test sticks:

1. Only one comparison line appears on the pregnancy test stick: indicating that you are not pregnant.

2. Two lines appear on the pregnancy test stick, that is, the comparison line and the detection line are both colored, and the detection line is obviously clear: it shows that the pregnancy has already begun.

3. No contrast line appears on the pregnancy test stick within 5 minutes: This indicates that the experiment is invalid or unsuccessful.

4. One dark and one light color on the pregnancy test stick: Generally speaking, if the contrast line is obviously clear and the test line is very light, it means that you may be pregnant, but it does not necessarily mean that you are pregnant. In this case, you need to test again every two days with a new pregnancy test stick to collect morning urine.

Therefore, if the pregnancy test stick shows one dark and one light, it means that you may be pregnant, but the result may not be accurate and you need to test it repeatedly before you can draw a conclusion.

Couples who are preparing for pregnancy are looking forward to the good news as soon as possible, so every time the wife uses a pregnancy test strip or a pregnancy test stick, she is excited but also nervous. But how to use pregnancy test strips or pregnancy test sticks to get accurate test results? What should you do if the pregnancy test stick shows two lines, one dark and one light? Is it pregnant or not? Let's find out:

The first pregnancy test stick to test is the woman's HCG value. After the sperm and egg are fertilized, the sperm and egg combine and settle in the uterus. At this time, the HCG value in the woman's body will increase to a certain extent, and the HCG component in the urine will also increase. In other words, whether you are pregnant or not depends on the status of HCG.

Secondly, when the pregnancy test stick shows two lines, it means you are pregnant, one line means you are not pregnant, and no lines means it is invalid, which is mostly caused by improper operation. So what do the two lines, one deep and one shallow, mean? One is that the urine collected may not be morning urine, which has the highest HCG concentration, so the test is more accurate; the other is that some women have too low HCG levels in the early stages of pregnancy, so the second line on the pregnancy test stick is very shallow, so you can just try again after a few days.

But there is one thing to be aware of. If the second line is still very shallow when tested later, you have to suspect whether it is an ectopic pregnancy. Inflammation in or around the fallopian tubes on both sides will cause the fallopian tubes to be blocked. The sperm and egg combine here and the embryo implants and grows into a test tube embryo. The pregnancy test stick will show two lines, one deep and one shallow.

If a woman who is preparing for pregnancy finds two lines, one deep and one shallow, during the pregnancy test, and her body is accompanied by symptoms such as amenorrhea, recurrent lower abdominal pain, and vaginal bleeding, she should go to the hospital for blood tests and abdominal ultrasound to see if an ectopic pregnancy has occurred. If you don't have these accompanying symptoms, don't worry too much, as pregnancy test tools can sometimes be wrong.
