Can a test strip detect pregnancy 10 days after intercourse?

For families who are preparing for pregnancy, the wait for the pregnancy test report is very long. Therefore, after having sex, they usually use pregnancy test tools to test immediately after a period of time to determine whether the female friend is pregnant. So, can pregnancy be detected 10 days after having sex?

Can I detect pregnancy 10 days after having sex?

Only a few people can detect the pregnancy at 10 days, while it is difficult for most people to predict it. Because it is 10 days into the pregnancy, the body's human chorionic gonadotropin has just begun to be produced and enter the urine. Because it has just been produced, the measurement at this time is extremely inaccurate (because most people will test weak positive at this time, and weak positive may also be caused by residues in the urine). Most measurements cannot determine whether you are pregnant. The best time to collect samples on site is 18 days after sexual intercourse, or 7 to 10 days after the next menstrual period is delayed.

Test principle: After the fusion of sperm and egg, the embryo implants in the uterine wall 6-8 days, and the HCG secreted by the embryo begins to enter the urine 7-10 days later, but due to the small amount, it is difficult to excrete, and it will not become obvious until 10-14 days later. It can be detected in the first 7 days after intercourse, usually in 18 days, and in very rare cases it may take 20 days or so.

Early pregnancy test: On the 7th day of a woman's pregnancy, a specific growth hormone (commonly known as HCG) can be detected in her urine, which is beneficial to maintaining pregnancy. In general, when urine is poured into the test hole on the pregnancy test paper, if a line appears in the comparison area of ​​the pregnancy test paper (some pregnancy test papers appear red, and some pregnancy test papers appear blue), it indicates that there is no pregnancy. On the contrary, if an obvious line appears in the test area, it indicates a positive result, indicating pregnancy. This type of test has the advantages of being rapid, convenient, flexible, and highly specific, and can avoid reactions caused by other glycoprotein hormones with a similar structure to HCG.

Urine pregnancy test: This method is actually the same as the principle of using early pregnancy test strips to test pregnancy, both of which accurately measure human chorionic gonadotropin (HCG) in urine. The success rate is over 90%, and it can usually be detected after 2 weeks of pregnancy.

Blood HCG test: During pregnancy, HCG will appear in both urine and blood. The success rate of blood HCG test is over 99%, and the accurate measurement time can be moderately advanced. In addition, blood HCG can detect abnormalities such as ectopic pregnancy, twins, and abnormal embryonic development.

According to the above introduction, you can have a very good understanding of whether the pregnancy can be detected on the 10th day. When you think you can't get pregnant, you should also look at the time of your menstrual period. At the same time, at this time, if there are some abnormalities in the body, you should go to the hospital for examination, so that you can know whether you are pregnant or not.
