Since it has been two weeks since you had sex, you can take an over the counter pregnancy test. Try to get one that says early detection, while it has been fourteen days, sometimes tests still don't pick it up that soon. Early detection tests will be more sensitive. If you get a positive test, you need to contact your doctor. If you get a negative test, wait for your period to come. If you don't get it, take another test to be sure. This is the only way to tell if you are pregnant or not. Good luck!
