After becoming pregnant, the hormone levels in a woman's body will continue to rise. An important indicator for checking pregnancy is human chorionic gonadotropin, which doubles in growth. Generally, early pregnancy test strips can be used to determine pregnancy. However, many people find that sometimes the color is dark and sometimes it is light. Why is the pregnancy test darker at night than in the morning?
Why is pregnancy testing done later at night than in the morning
During pregnancy, a significant increase in human chorionic gonadotropin levels is detected, indicating pregnancy. Under normal circumstances, people will use early pregnancy test strips for examination, and the results of the examination will be influenced by various factors, and within a certain period of time, human chorionic gonadotropin will gradually increase. The results of the pregnancy test are relatively shallow now, and it may be due to the short duration of pregnancy. You can calculate your pregnancy time based on your menstrual period.
How to use pregnancy test paper
Collect urine in a clean and dry container. Urine at any time is suitable for this experiment, especially the first morning urine is the best; Dip the end of the test strip marked with an arrow into a container containing urine, and after about three seconds, take it out and place it flat. Observe the results within 30-5 minutes; According to the instructions on the product, if only the reference line appears, it indicates that there is no pregnancy; Both the control line and the detection line show color, and the detection line shows clear color, indicating pregnancy; No color lines appear, indicating that the test has failed or failed.
How long can a pregnancy test paper be used to determine
The working principle of pregnancy test paper is to detect HCG value, which is the value of human chorionic gonadotropin. This hormone is produced by the placenta and usually appears in the urine a few days after pregnancy. Usually, HCG is only detected in urine about 7 days after sexual intercourse, but at this time the concentration is low and it is difficult to detect with a pregnancy test paper. Therefore, it is recommended to wait at least 2-3 days for the concentration to increase, which means that pregnancy can be detected with a pregnancy test paper as early as 10 days. If the ovulation and implantation times are delayed, it may take about 15 days to detect pregnancy.
Firstly, it is important to use pregnancy test strips correctly, as different manufacturers may produce varying shades of color. Secondly, early pregnancy testing should be conducted based on the duration of pregnancy, as the color may darken over time. In the early stages of pregnancy, it is important to monitor your HCG and progesterone levels in a timely manner, as these indicators can reflect whether your progesterone levels are normal.
