Can pregnancy be detected after one week of intercourse?

Some people think that the test can only be done after the menstruation is delayed for more than 10 days, while others think that the test can be done one week after intercourse. So when can you test whether you are pregnant after intercourse? This is what many women who are preparing for pregnancy want to know. Can pregnancy be detected in generally one week? And which method of detecting pregnancy is the most accurate?

Can I detect pregnancy in one week?

If you get pregnant after having sex, the process of sperm and egg fertilization itself takes about 12 hours, which means that the entire fertilization process must be completed 24 hours after ovulation. It takes 7 to 8 days for the fertilized egg to swim from the abdominal wall of the fallopian tube to the uterus and implant in the mother's body. Only then is it called conception. So it takes at least 7-8 days from fertilization to pregnancy, but no more than 9-10 days.

The egg begins to secrete human chorionic gonadotropin (HCG) on the 6th day after fertilization. This hormone is produced by the placenta. At the beginning, the amount secreted is relatively small, so it is not easy to detect. It will not be secreted significantly until 10-14 days. Because HCG exists in the blood and urine, but blood hCG appears earlier than urine hCG. Blood HCG testing can be performed 10 days after intercourse, while urine HCG testing requires 14 days. Therefore, it is impossible to detect whether you are pregnant one week after intercourse.

Which method is most accurate for detecting pregnancy?

If you want to get the most accurate answer, it is best to go to the hospital for B-ultrasound examination and blood HCG test, which is the most reliable and accurate. You can go to the hospital for a blood test for pregnancy 10 days after having sex, and the result will be available two hours after the blood is drawn. However, blood tests for pregnancy also have their flaws. This method can only detect pregnancy but cannot determine whether it is an intrauterine pregnancy. . Using B-type ultrasound to check pregnancy is convenient and accurate, and a diagnosis can usually be made around 5 weeks of pregnancy. Type B ultrasound can not only diagnose normal pregnancy, but also diagnose ectopic pregnancy.

The above is an introduction to whether pregnancy can be detected in one week. Generally speaking, the longer the time after intercourse, the more accurate the test result will be. This is mainly because each woman's physical fitness is different, resulting in different timing and amount of HCG secretion. Therefore, sometimes a negative test result may appear even if you are pregnant. Therefore, female friends may wish to take a pregnancy test 10 days after the menstruation is delayed or more than 2 weeks after intercourse. The result will be more accurate.
