    if it doesn't come Sunday you should be able to test then. if it still doesn't come after several more days, try the test again. Good Luck

    Well, first you gotta know how the test works. Briefly: the home pregnancy test (HPT) works by detecting a hormone called human chorionic gonadotropin (hCG.) When an egg is fertilized, it takes about 6 to 12 days to implant in the uterus, and then it begins to secrete hCG. It takes another day or two for enough hCG to build up and make its way into your pee. So, generally speaking, the earliest you can expect a positive HPT is 8 days past ovulation ("DPO") and the latest would be about 16 DPO. It is possible to get a positive test earlier or later, but not as common. In my experience, if you use a sensitive "early" test (anything that detects 25 mIU/mL of hCG or less) you can test around 12-14 DPO and feel reasonably secure with your results (the later you test, the more secure you can feel in its accuracy.)

    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.)

    Note: some HPT's say "test 5 days before your period is due!" or some such thing. Please note they are assuming a textbook 28-day cycle, with ovulation on Day 14. "5 days before your period is due" thus really "translates" to 10 DPO.

    No, you can take a test and it should show..Good Luck..but just know that even if you do get your period, you could still be pregnant because of the close time frame..that happened to me..
