Not possible: It is not possible to tell that you are pregnant 3 days after having sex. It takes the sperm 6-12 hours to reach the egg. Once successful, it takes the embryo another 4 days to reach the uterus. It must then implant on day 5 and by day 8, start making bHCG, the hormone of pregnancy which you will test for in your urine. You have missed the window for emergency contraception so you must wait.
