If you know the date of your last menstrual period, add twenty-three days to give you an approximate conception date. With only 1 week between your sexual encounters with two different men, it will be very difficult to determine which one is the father. You can do a paternity test on a maternal blood sample after 9 weeks. You will need both of the men's samples as well.
