Pregnancy test: While having sex on day 18 of a 24 day cycle makes it highly unlikely to conceive, there is no way to be sure about when ovulation happened. Home urine pregnancy tests become positive as early as a week after unprotected sex. If negative, the test should be repeated in another week and would then be positive in case of a pregnancy.

Maybe not, but...: A urine pregnancy test, done correctly, gives a reliable result 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a period. If done sooner, a positive result is likely real, but a negative result may be due to testing too soon, and thus lead to a repeat test. If a woman gets her normal regular period, then she is not pregnant, and a test is not needed.
