It is not possible to detect pregnancy after 6 days of intercourse because the time is relatively short. As far as possible, a urine HCG test, also known as a pregnancy test, should be performed about 12 days after intercourse to rule out conception. It takes about 12 days for the sperm and the egg to unite and reach the mother’s bloodstream and then the urine. If it is too early, it is an invalid test, and even if you want to take a blood test to determine if you are pregnant, you must take a blood test 8 days after intercourse to determine if there is a high HCG level, which is more accurate. As far as possible, you should be patient and not overly nervous and anxious, so as not to cause delayed menstruation, which may also affect the factors that do not allow conception, so you must relax, exercise and take a walk to divert your attention and increase your resistance.
