If there are still six days left before the menstrual period, even if the sperm and egg have been united, the pregnancy cannot be detected through laboratory tests because the fertilized egg has not yet been laid, and only after it has been laid can the changes in the hormone level in the body be detected and the pregnancy can be known. Therefore, it is recommended that if you want to use the morning urine for early pregnancy test, it is better to test 20 days after intercourse, the positive rate will be higher, if you use blood test, it is recommended that it is better to do it half a month after intercourse.
