If you do not chart or monitor your fertility in any way, and you think you may have conceived, you should wait 19 days (or longer) after having sex to test. Why 19?! Sperm can live approximately 5 days in the proper environment; if the sperm managed to live until you popped an egg, the actual conception could have taken place several days after the sex act that got the sperm there. To make sure you're not testing too early, assume the sperm had very long lives (5 days is considered a very long sperm life) and that conception occurred then. Then allow 14 days for the embryo to implant and develop enough hCG to show up on a pregnancy test (96% of pregnant women will test positive by then.)

It depends on when she ovulated. Sperm can live for 5 days, so if sex was 5 days before ovulation, she should wait at least 15 days, until she gets to 10 days past ovulation. If she had sex the day of ovulation, then wait at least 10 days. I got positives both times, at 10 days past ovulation using sensitive tests.
