Female friends may become pregnant after having sex, especially if they did not use any contraceptive methods during previous sexual intercourse, the chance of pregnancy will be higher. There are also many women who are preparing for pregnancy and will care more about the time of pregnancy. So, how many days after menstruation can pregnancy be detected? If sexual friends want to know the results after the pregnancy preparation period, the easiest way is to use an early pregnancy test strip to calculate it. Generally speaking, it takes about a week after intercourse to detect pregnancy using an early pregnancy test. If you want to increase the accuracy of the test, it is recommended to wait about 10-15 days after intercourse. At this time, the result can be trusted. After pregnancy, you need to use your own urine to detect pregnancy with an early pregnancy test strip. At the beginning of pregnancy, choose the first urination in the morning as the sample for testing, and the result may be more accurate. If it has been a long time since the sexual intercourse, for example, more than ten days have passed, the urine at any time of the day can be used for testing. Try it several times to see the results. After getting the same results, go to the hospital for a detailed examination. The test paper can be detected in the first few days Like professional medical tests, the principle of pregnancy test is to test the HCG value, that is, the value of hcg gonadotropin in the body. The body's hCG gonadotropin 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 will become increasingly obvious from 10 to 14 days. (HCG value can also be measured through blood test, and it is much more accurate). Although many pregnancy test strips indicate that women can take a pregnancy test one day after missing their normal menstrual period, in fact, not all pregnant women excrete the same rate and amount of HCG hormone, which varies from person to person. 1. The morning urine test is more accurate for women who have recently become pregnant. But for women who have been pregnant for some time, urine at any time of the day can be used for testing. 2. It usually takes about 7 days for the embryo to implant. In other words, you can test whether you are pregnant on the day of pregnancy (equivalent to 7 days after having sex). 3. It can be used 7 days after the menstrual cycle is delayed or 10 to 14 days after intercourse, or at the beginning about 33 days after menopause. If the early pregnancy test cannot show whether you are pregnant, you can do another test about 37 days after menopause. How to use pregnancy test strips? The first step is to read the manual carefully before conducting the test, and collect and restore the test reagents and urine samples to room temperature (20℃-30℃) before use. The second step is to remove the test strip from the original foil packaging bag and use it as soon as possible within 1 hour. The third step is to insert the test reagent strip into the urine sample collection hole in the direction of the arrow mark. Note: The urine level must not exceed the marked line on the test reagent strip. Step 4: After at least 5 seconds, remove the device and place it on a clean, flat surface to observe the result. Step 5. Wait for the dark purple band to appear. The test result should be loaded in 3 minutes. The judgment will be invalid after 10 minutes. |
