Why is the test strip white on the 6th week of pregnancy

Many people use early pregnancy test strips in the early stages of pregnancy. This method is simple and easy to operate, and you can usually test whether you are pregnant at home. For those who use the early pregnancy test strips for the first time, they don’t know how to check and may encounter various problems. For example, why is the pregnancy test strip white? This is a problem that many netizens will encounter. The following is a detailed analysis for everyone.

Why is the pregnancy test paper white?

Theoretically, if you are pregnant on the 9th day of ovulation, which is the 23rd day of your menstrual period, you can use a more sensitive method to detect whether you are pregnant. If the early pregnancy test paper shows a white version, it means that you have not detected that you are pregnant. If you have not detected that you are pregnant, it should be said that the version is white. If the early pregnancy test paper shows a white version, it may be that the test time is a little early, so it cannot be detected. Generally, after the egg cell is released from the ovary, it can survive in the fallopian tubes for 1-2 days to wait for fertilization; the male sperm can maintain the fertilization ability for 2-3 days in the female reproductive system. After the egg cell and sperm combine, they will not immediately become test tube embryos, but it will take some time to be detected. Therefore, to be on the safe side, it is generally more accurate to have sex 14 days after ovulation in the early stages of pregnancy.

The early pregnancy test paper shows a blank screen, which means that you are not pregnant at this time. Of course, it cannot be ruled out that it is too early to detect it, but don't put too much pressure on yourself, just take it as it comes. Generally, you can use an early pregnancy test strip to detect whether you are pregnant 14 days after having sex. I suggest you test again after a few days.

The principle of using early pregnancy test strips for pregnancy testing is to test the hCG value, that is, the value of hCG gonadotropin in the body. This type of growth hormone is produced by the embryo and usually appears in the urine a few days after pregnancy. However, due to the small amount, it is not easy to test it at the beginning, and it becomes increasingly obvious after 10-14 months. For women who are about to get pregnant, it is generally recommended to test the first urine in the morning as the result is more accurate. But for women who have been pregnant for some time, urine at any time of the day can be used for testing.

What is the reason for the print on the early pregnancy test paper after the white version?

There is a mark behind the white version of the early pregnancy test paper, which is the main manifestation of weak positive. Early pregnancy test strips can detect human chorionic gonadotropin (HCG) in urine to determine whether you are pregnant. So, what does a weak positive on an early pregnancy test mean? A weak positive on an early pregnancy test means that if it is negative, it means you are not pregnant, if it is positive, you are pregnant, and if it is a weak positive, it means you may be pregnant, but if the standards are not very perfect, the test results are not very certain.

Generally speaking, the HCG value in early pregnancy is not very high, so the early pregnancy test paper will show a weak positive. If you are not sure, you can wait a few more days before testing. If you suspect you may be pregnant, the best way is to go to the hospital for a reliable blood HCG or urine HCG test. The actual operation itself may lead to a significant reduction in detection accuracy due to improper detection time, environment and testing standards.

In order to make the early pregnancy test paper weak positive test results correct, pay attention to the following aspects when using the early pregnancy test paper:

1. If the pregnancy is just beginning or there is a possibility of ectopic pregnancy, the HCG level in the body is generally slightly low. The test sample needs to be left alone for more than 3 minutes, and you must carefully distinguish whether there is a weak positive on the early pregnancy test paper, and the printed color band in the test area only appears faintly.

2. If the early pregnancy test paper is stored for too long (more than 1 year) or is not stored properly (such as moisture), and is not stored under normal temperature conditions, it may become invalid and a false negative test result may easily occur.
