No. You need to wait at least 14 days after intercourse to see if you are pregnant. To ensure the best results for a home pregnancy test:
Take the test in the morning, if possible, because your hCG (pregnancy hormone) levels are at it's highest
Don't drink a bunch of fluids before taking the test because it will dilute your urine and can affect the results
Take the test no more than 1 day before expected period. OR 14 days after intercourse (sex). Although some test say that you can see results up to 5 days before your missed period, the percentage of accuracy is very low.
urinate for as long as possible on the foam-like strip
Check the results in the window frame of time suggested by the instructions of the pregnancy test.
