Not possible to tell: Depending on your HcG levels and the sensitivity of the test it is possible to get a positive test 7 days after conception. So, with that fact, it is impossible to tell from the information you have given which encounter led to the pregnancy. An early U/S MAY give a better "guess" but this is something you may never know. If male partner was different - then paternity testing would be advised.
