how soon should I buy a pregnancy test after sex?
You can wait for 14 days after sexual intercourse. You may be able to get a result on an early pregnancy test. Visit http://www.nhs.uk/chq/Pages/948.aspx?CategoryID=54&SubCategoryID=140 for more information on pregnancy test.

At least two weeks. Some pregnancy tests will show results 19 days after unprotected sex.
