Early pregnancy test paper shows light pink mark

If you don't take any contraceptive measures during sex, it may lead to pregnancy. Some people want this to happen, while others don't. If your menstrual period is delayed for more than 5 days, you can use a pregnancy test to roughly determine whether you are pregnant. So, what is the reason for the light pink mark on the early pregnancy test paper? Let’s take a look below.

Generally, one bar means you are not pregnant, but two bars are very obvious and it means you are pregnant. For women of normal childbearing age who have sexual activity, when menstruation is delayed for more than 10 days, pregnancy should be considered first. Generally, the presence of double bars indicates a positive result, which means pregnancy.

How to read the results of an early pregnancy test

The test result was positive: pregnancy. A red reaction line appears in the test area and the control area.

Weak positive test result: pregnancy is possible. A red line appears in the reaction area, but the color is lighter than that of the control area.

The test result is negative: not pregnant. Only one red reaction line appeared in the control area.

Invalid: No red reaction line appears on the test paper, or only one reaction line appears in the detection area, indicating that the test has failed or the test paper is invalid.

The test results displayed after 10 minutes have no clinical significance. In addition, pregnancy test strips from different manufacturers may be different, so it is best to refer to the instructions for specific usage.

When is the earliest time to use the pregnancy test strips?

1. Before explaining the earliest time to use the early pregnancy test paper, let's first understand the detection principle of the early pregnancy test paper: human chorionic gonadotropin (HCG) is a glycoprotein produced by the placenta during pregnancy and can be excreted from the body through the glomerulus, so the measurement of HCG in urine is a reliable indicator for diagnosing pregnancy. The early pregnancy test paper adopts nano-colloidal gold technology and applies the chromatography double antibody sandwich method to detect the HCG concentration in urine to determine whether you are pregnant.

2. Complete human chorionic gonadotropin (HCG) is produced entirely by the syncytiotrophoblast of the placental chorion. Its main function is to stimulate the corpus luteum, which is beneficial to the continuous secretion of estrogen and progesterone, so as to promote the formation of uterine decidua and make the placenta grow and mature. HCG begins to be secreted about 6 days after fertilization and reaches its peak around 60-70 days. It increases rapidly during the first 8 weeks of pregnancy to maintain the pregnancy. After about 8 weeks of pregnancy, HCG gradually decreases until it reaches a relative stability around 20 weeks.

3. So theoretically speaking, the 9th day of ovulation is the 23rd day of menstruation. If you are pregnant, you can use an early pregnancy test to detect whether you are pregnant, but it is recommended to test it one month into the pregnancy or 7-10 days after menstruation for relative accuracy. When using it, you should choose the first urination in the morning for higher accuracy.
