After the pregnancy is confirmed or the pregnancy test is positive, the test may become lighter after 10 weeks of pregnancy.
After pregnancy is confirmed, the pregnancy test will not become lighter for a short period of time, because the pregnancy test is to detect the HCG value in the body to determine whether or not the pregnancy, and after pregnancy, the HCG in the urine is gradually increased, so for a period of time the pregnancy test will be deepened in color.
The color will deepen over a period of time. Generally, it will reach a peak at about 10 weeks of pregnancy, and then it will decline, and the test may become lighter at that time.
If the color of the pregnancy test becomes lighter in early pregnancy, it may be due to the short duration of pregnancy or the possibility of poor development of the child, it is recommended to consult a doctor in time, through the examination of blood HCG, progesterone, ultrasound to see the development of the child, if there is any abnormality, consult a doctor in time.
