Most doctors recommend that you wait until the first day of your missed period before taking a urine pregnancy test. This is usually about two weeks after conception. However, some tests are more sensitive than others and can be taken earlier.
Most IVF clinics want you to wait 14 days after the egg collection before doing a pregnancy test (a test which detects the HCG hormone produced by the cells of the developing embryo !) But you can do a pregnancy test much earlier too.
